Field of the Invention This invention relates to binary mixtures 6c. cellulose esters with aiiphatic polyesters or with aromatic-aliphatic copolysates as well as ternary mixtures of cellulose esters with aliphatic polyesters and / or with aromatic-aliphatic copolyesters and / or with other polymers. These resins are useful for extruded or molded plastic objects, fibers, or films. This invention also relates to the random aromatic-aliphatic copolyesters which are useful for extruded or molded plastic objects, fibers or films. On the other hand, various additives may be added to the aromatic-aliphatic mixtures or copolyesters to improve the properties such as biodegradability or the water vapor transmission rate. Background of the Invention It is well known that cellulose esters are important as commercial plastics and as fibers. In general cellulose steres are used in applications made of plastic where hard but clear plastics are required. For example, cellulose steres are used in tool handles, frames for eyeglasses-toys, handles for toothbrushes, and the like. All these applications require a combination of high melting and transition temperatures to the glass as well as good resistance to stress and a high modulus. The formulations based on cellulose esters that provide plastic films with low modulus but good tensile strength while maintaining sufficient melting and glass transition temperatures (Tg) to allow thermal processing are well known. . The cellulose-based formulations that allow thermal extrusion of the fibers are also generally known. Due to high AS and high melting stability of many cellulose steres, plasticizers, such as dioctyl adipate or triphenyl phosphate, are often added to the cellulose ester to lower the melting temperatures during the fusion processing of the polymer. Although this technique is effective, the addition of a monomeric plasticizer often causes secondary problems related to extractable or volatile plasticizers, such as dye run-off during extrusion by melting or long-term dimensional stability (deformation) in a object made from a cellulose ester. Most of the basic requirements for the -miscibility is that the energy released when mixing is negative (kG < r?). Although on the surface it seems that polymer miscibility with polymer might be common, in reality there are only few known miscible binary mixtures and even less known are the systems of ternary mixtures (Brannock, G.R.; Paul, D.R., Macromolecul * s (macromolé'culae), 23, 5240-5250 (1990). The discovery of binary mixtures or miscibles ternary are very rare. The classical experimental techniques for the determination of the miscibility of the polymeric mixtures comprise the determination of the optical clarity of a film made from the mixture, the measurement of the temperature of the transisc? N to the glass by an analysis technique. thermal analysis, such as a thermal, mechanical and dynamic analysis (DMTA), or differential scanning calorimetry (DSC). When a mixture is miscible, the films made from the mixture will generally be clear. In addition, the mechanical properties of a mixture, such as tensile strength or tangential modulus, are often intermediate factors between the components of the mixture. In addition, an amorphous -miscible mixture will show a single intermediate factor of Tg between those components of the homopolymers, whereas a partially miscible or immiscible mixture will show multiple components of Tg. In the case of a totally immiscible mixture, the components of Tg will be those of the homopolymers. For partially miscible mixtures, the Tg components will be intermediate values corresponding to the partially miscible phases rich in one of the components. The variation in the binary mixture of Tg can be modeled by the Fox-Flory equation, Tg12 = Tg1 (^) + Tg2 (W2), where Tg.- is Tg of the -mix, Tg. and Tg2 are the Tg of each one of the components of the homopolymers, and W. and W2 are the porsientos in weight of each component of the mixture. Although the Fox equation does not take into account the specific interaction between the co-ordinators, the Gordon-Taylor equation, Tg12 = Tg? + [kW2 (Tg2 - Tg12) / W.] where k is a constant, it is often preferred in the analysis of the mixture. For a well mixed, homogeneous system, a representation of Tg .. against W_ (Tg2 - Tg12) / Vedara as a result a straight line inclined which is equal to Tg.,. The constant K is often a measure of the secondary interactions between the components of the mixture. When k is equal to one, the Gordon-Taylor ecofriend reduces to a simple average weight of the Tg component. Miscible mixtures of cellulose esters and other polymers are generally unknown. The most notable exceptions include the works described by Koleske et al. (US Patent 3,781,381 (1973)), by Bogan and Combs (US Patent 3,668,157 (1972)), by Waniczek and, co-workers (US Patent 4,506,045 (1985)), and by Wingler et al. (U.S. Patent 4,533,397 (1985)). Koleske et al. Reported that the mixtures, formed by a molten solids of the mixtures of cellulose ester and a polycaprolactone, are miscible. A subsequent work described by Hubbell and Cooper (J. Appl. Piym, Sci., 1977, 21, 3035) demonstrated that mixtures of polycaprolactone with cellulose acetate butyrate are actually immiscible. Bogan and Combs have reported that the block copolymers of the polyether polyester blends form miscible mixtures with some cellulose esters. A criticism of the Bogan and Combs invention was the use of an elastomeric block copolymer and reported that the corresponding homopolymer elastomers are incompatible with cellulose esters. Aniczek, have reported that polyester carbonates and copolymers of polyester carbonates form irascible mixtures with many of the cellulose esters and are useful as thermoplastic resins. Wingler et al. Reported that contact lenses can be made up of mixtures consisting of (A) between 97, -70% by weight of one or more cellulose esters and (B) between 3-30%. by weight of an aliphatic polymeric compound having ester portions, carbonate portions or both ester and carbonate portions in the same polymer chain. The invention by Wingler et al. Is limited to aliphatic polymeric compounds; no reference is made to the random copolymers consisting of aliphatic diacids, aromatic diacids, and suitable diols or polyols. The invention of Wingler is further limited by esters mixed with cellulose having a hydroxyl weight percentage of 1.2% to 1.95% (DSQH = -0.111-0.19 where "DS" or "DS / AGU" refers to the number of substituents per anhydroglucose unit where the maximum amount of DS / AGU is three). The Win'ler et al. Invention is also limited to miscible binary mixtures and the ratio of the composition of the mixtures (between 3-30% of the aliphatic polymeric compound). No reference is made to mixtures containing immiscible co-polymers in which the immiscible component is useful for improving properties such as water vapor transfer rate or biodegradability. The immiscible mixtures of cellulose esters and aromatic polyesters have been described by Pollock et al. (US Patent 4,7 / 0,931 (1988)) and are useful in applications as paper substitutes. In disposable items to be used only once. Examples of such disposable articles include articles such as baby diapers, incontinence briefs, sanitary napkins, ta pax, bed covers, orifices, bandages, food bags, sheets for agricultural manure and the like. Examples of other disposable items include shaver handles, toothbrush handles, disposable syringes, fishing line, fishing net, packaging, cups, double-shovel buckets, and the like. It is desirable for disposable articles without environmental perseverance. Disposable articles are typified by disposable diapers. A disposable diaper typically has a thin covering of a flexible polyethylene film, an absorbent filler as the intermediate layer, and a porous inner liner that is typically a nonwoven polypropylene. The construction of the diaper also requires tabs or tapes for securing the diaper (typically of polypropylene) as well as various elastomers and adhesives. Although the absorbent filler is generally biodegradable or easily dispersed in an aqueous environment, currently neither the inner nor the outer coating nor any of the other parts such as adhesive tapes or tabs will degrade by microbial action. Accordingly, disposable absorbent materials such as l-diapers accumulated in sanitary landfills and deposit a large pressure in the waste systems. Other disposable items such as plastic bags or plastic fertilizer sheets suffer similar problems. Diverse;? Studies have shown that cellulose or those cellulose derivatives with a low degree of substitution, that is, less than one are biodegradable. Cellulose is degraded in the environment by aerobic microorganisms as well as by anaerdbics. Typical end products of microlock degradation include cellular biomass, methane (ana-erdbium only), carbon dioxide, water, and other fermen-tacidn products. The final products will depend on the type of environment as well as the type of microbial population that is present. However, it has been reported that cellulose steres with DS greater than one are completely resistant to attack by microorganisms. For example, Stutzenberger and Hahler (J. Appl. Bacteriology, 65, 225 (1986)) have reported that cellulose acetate is extremely recalcitrant to attack by Thermomonospora curvata. Polyhydroxyalkanoates (PHA.), Such as polyhydrox butyrate (PHB), polycaprolactone (PCL), or polyhydroxybutyrate-polyhydroxyvalerate copolymers (PHBV), have been known for at least twenty years, with the exception of polycaprolactone, they are generally prepared biologically and have been reported as biodegradable (M. Kunio? a and collaborators, Appl. Microbiol. Biotechnol., 30, 569, (1989)). Polyesters prepared from aliphatic diacids or a corresponding carboxylic ester; of lower alcohols and dicles have also been reported as biodegradable. For example, Fields and Rodriguez, ("Proceedings of the -Third International Biodegradation Symposium," JM Sharpley and AM Kaplan, Eds., Applied Science, Barking, England, 1976, 0. 775). Prepared diacid esters of C2- -C12 bound with C4-C12 diols and it was found that many were biodegradable. Aliphatic polyesters have been used in very few applications mainly because of their low melting point and low glass transition temperatures - (generally less than 65 ° C and -30 ° C, respectively). At room temperature, the physical form of many aliphatic polyesters is like a viscous, thick liquid. Therefore, aliphatic polyesters are generally not expected to be useful. On the other hand, aromatic polyesters, such as poly (ethylene tert-phthalate), poly (cyclohexanedimethanol-ethaftalate) and poly (ethylene-terephthalate-co-isottalate), have proven to be very useful materials. However, aromatic polyesters are generally very resistant to biodegradation (J. E. Potts in "Kirk-Othmer Encyclopedia of Chemical Technology", supra, Vol. Wiley-Intersci nce, New York, 1984, pp. 626-668). Block copolyesters containing aromatic structures such as aliphatics have been prepared and shown to be biodegradable. Examples of aromatic-aliphatic block ethers copolyesters include the work of Reed and Giiding (Polymer, 22, 499 (1981)) which employs a poly (ethylene-, terphthalate) / poly- (ethylene oxide) wherein these Block copolymers were studied and found to be biodegradable in vitro. Tokiwa and Suzuki have investigated block copolyesters, such as those derived from. poly. { caprolactone) and poly (butylene terephthalate) and were found to be degraded by a lipase (J. Appl. Polym, Sci., 26, 441-448 (1981)). Presumably, biodegradation is dependent on the aliphatic blocks of the copolyesters; the blocks consisting of an aromatic polyester are still resistant to biodegradation. The aromatic-aliphatic random copolyesters have not been investigated in relation to this. While random copolyesters with low levels of aliphatic diacids are known (ie, Droscher and Hprlbeck, Ange. Makromol, Chemie, 128, 203-213 (1984)), copolyesters with high P > > 30%) of aliphatic dicarboxylic components are generally unknown. Copolyesters with no less than 40% of the aliphatic dicarboxylic acid components have been described in adhesive applications; however, these copolyester adhesives contain at least two dialcohol components with the purpose of achieving the desired adhesive properties (Cox, A., Meyer, M.F., in U.S. Patent 4,966,959 (1990)). There are many references for the preparation of films from polymers such as polyhydroxybutyrate (PHB). The production of films generally from PHB polymers comprising the solvent melt mainly because the polymers tend to remain sticky and viscous for a substantial time after the temperature has fallen below the melting point of the PHB. To avoid this problem, Martini et al. (U.S. Patent Nos. 4,826,493 and 4,880,592) teach the practice of co-extruded PHB with a non-viscous thermoplastic. Such thermoplastics remain as a permanent layer on the PHB film or can be a sacrificial film which is removed upon following the extrusion. The PHB has also been reported to be useful in the preparation of disposable articles. Potts has described (US Patent Nos. 4,372,311 and 4,503,098) that water-soluble polymers such as poly (ethylene oxide) can be covered with water-insoluble polymers biodegradab * Le, such as PHB. In these inventions, the PHB layer, which is different from the water-soluble layer, is degraded by exposure with the soluble Qapa to the water which will then be dispersed in an aqueous m-dio. There are other reports on the preparation of biodegradable barrier films for use in disposable articles. Comerford et al. (US Patent 3,952,347) ha. described that finely dividing biodegradable materials such as cellulose, starch, carbohydrates, and natural gums can be dispersed in a matrix of non-biodegradable film-forming materials that are resistant to water solubility. Wielicki (US Patent 3,602,225) teaches the use of barrier films made from cellulose films regenerated with plasticizers. Comerford US Patent 3,683,917) teaches the use of a cellulosic material coated with a water repellent material. There is a need in the market for thermoplastics that are useful in film, fiber and molding applications. For these applications, it is desirable that the thermoplastic mixture be processable at a low melting temperature and have a high temperature for the transition to the glass. These thermoplastics will not contain extractable or volatile plasticizers. In addition, there is a need in the market for a material to be used in disposable articles such as diapers, diapers and the like. As an example, different films prepared from the polymers, such as PHB, whose material is arranged to be treated in the solvent melt as in melt extrusion. In the extrusion? by fusion - from this material, coextrusion with another thermoplastic material may not be a requirement. The barrier properties of this novel biodegradable material will be adequate in order that coating with a water-insoluble polymer is not required. The novel material will be completely dispersed in the environment and will not require polymeric coatings soluble in water. The mechanical properties of the material should be such that films with low modulus but with high tensile strength can be prepared.

Naturally, the miscibility range of a particular mixture can change as the molecular weight of a component of the mixture is changed.

Mixtures that thermally form compounds can be used for extrusion melting of the fibers. The fibers and films prepared from the blends or from the AAPEs of the present invention are useful in applications where the films and protective barrier are removable. For example, they can be used in absorbent articles such as diapers, babies, incontinence trunks (nappies), sanitary napkins, tampaxs, bed covers, urinals, windows and the like. The films, fibers, AAPE and bio-degradable mixtures of the invention are particularly useful in articles that are subject to environmental considerations. The blends and / or films of the invention may also be useful for making non-absorbent articles such as packaging materials, (e.g., foam sheets for packaging), food bags, garbage bags, sheets for agricultural fertilizer, base film for tapes and photographic films, as well as sdli? os plastic articles, such as case for cameras and syringes.

The biodegradable materials, such as the preferred barrier films of this invention, are materials that consist of the compounds which, by catalyzed microbial degradation, are reduced in fiber or film strength by the reduction in the size of the polymer to the monomer or the short chains that are then assimilated by the microbes. In an aerodic environment, these monomers or short chains are finally oxidized to C02, H20 and a new cellular biomass. - In an anaerobic environment the monomers or short chains pr last are oxidized to C02, H2, acetate, methane, and, to a new cellular biome. Successful biodegradation requires that direct physical contact should be established between the biodegradable material and the active microbial population or by the enzymes pro- vided by the active microbial population. An active microbial population useful for the "acidification" of films and mixtures, the invention can generally be obtained from any facilities for the treatment of wastewater in which the effluents (stream? e? esecho) are. with a high level of cellulose materials. Moreover, the success of bio-acid requires certain minimum physical and chemical requirements to be met such as a suitable pH, temperature, concentration, oxygen, nutrients at low temperatures, and wet level ?. We have found that certain cellulose esters are bioegradable in conventional facilities for treatments? Echos? And water and in an enrichment system in vitro and for this reason they are particularly useful in the preparation? to be used as films? and barrier. fibers in the articles? We have also found that many mixtures and AAPEs are degraded in a composite environment and therefore are useful in the preparation of materials to be used as materials that do not permeate the environment. The following examples are to illustrate the invention but will not interpret as a limitation. EXAMPLES In the following examples, the mixtures were prepared by three general methods: (i) the mixed components were stirred together before the formation of the compound at an appropriate temperature? in a Rheometric Mechanical Spectrometer. The resulting resin is a typical base having a particle size of 5 mm and a portion is compressed between the metal plates at a temperature higher than the temperature, and the resin is melted to form the compressed film. by merger. (ii) the mixtures of the cellulose and polyester stresses were prepared by forming the compound with an extruder? eblet Werner-Pflei? erer propeller 30 mm. The typical process is as follows: Two separate feeding systems, one for the cellulosic material and the other for the polyester, were used for this method, and they were mixed by mixing. The cellulose ester was added as a powder in Zone 1 and the polyester was added as a viscous liquid in Zone 3. The cellulose ester was added in the desired ratio using an AccuRate feed. through a hopper in the barrel? the extruder. The polyester previously < = heated under a nitrogen atmosphere and emptied into a heated feed tank. Was the polyester kept under the atmosphere of nitrogen and gravel? and was fed through a stainless steel pipe to a pump, which transfers the material through a stainless steel pipe ((1.27 cm. in its outside diameter) through Extruder barrel All the pipes in this feeding system were heated and insulated.The production ratio? the extruder is in the range? 4.54 to 22.70 kg / h.?

Table I shows that each of the samples comprising 20% aromatic-aliphatic copolyesters (steps 1), 3, 5, 8, 14, 17, 20, 22, 27 and 29) had an experimental Tg12 that was 14 to 37 ° C higher than the g-2 calculated for each mixture.

At very high levels of the aromatic-aliphatic copolyethers (operation 26), a single Tg was observed. Such analysis suggests that mixtures of cellulose esters with aromatic-aliphatic co-gypses comprising an aliphatic diamine with C5 are generally miscible in a range that varies approximately? 30 to 55% when the aromatic portion? The copolyesters are approximately 15 to 30%. The mixtures of the aliphatic-aromatic copolyesters that they buy in an aliphatic manner, and the C5 outside the range, and 30 to 55% show levels of variation and miscibility. The mixtures you buy in other aliphatic acids will also show levels of variation in your miscibility through a wide range. The miscibility? The mixture is also strongly? ependent? the molecular weight? the polyester. In general, a polyester? And I.V. The low weight will give us a wide range of miscibility. Cellulose esters typically have a higher WVTR [>500 g / mil / 100 inch uring 24 hours (thousand = 25.4 microns, inch = 2.54 cm). Table II also showed that all the aromatic-aliphatic / CAP copolyzer blends have a WVTR less than 500 g mil / 100 inch for 24 hours (one thousand -25.4 microns, one pulsed = 2.54 cm). Table II also shows that a wide range of physical properties is possible for the prepared materials of the mixtures depending on the components of the mixture and the composition of the mixture. Many of the mixtures of aromatic-aliphatic copolyesters gave rise to unusual and unusual physical properties. For example, the tangential modulus (Table II) for mixtures with 20% were, for the most part, surprisingly high relative to the CAP [2.1 x 10 5 psi (Psi = 0.07 kg / cm2)] except for the mixtures they purchased in a PTG (T) [70/30] and a PTG (T) [60/40], -all the tangential modules were above? 10 5 psi (psi = 0.07 kg / cm2). Even more surprising was the tensile strength for the blends with 20%. With the exception of the mixture PTG (T) [60/40], the tensile strength of these mixtures were all above 5.0 x 10 psi 2 (psi = 0.07 kg / cm); in some cases resistance to tension is reduced in relation to the CAP (5.5 X 10). In general, with the exception of the mixtures of PTG (T) [60/40], all the mixtures that they buy in 20%, the copolyetic-aliphatic aroma, behaved very similar to propionate and acetate. e cellulose. In fact, we can substitute 20% for a copolyester, which generally has many properties, is physical rather than the components of the mixture, and this cellulose, for cellulose, without diminishing the mechanical properties, and in some cases were improved the property? is inherent mechanical propionate? and acetate? e cellulose.

Essays? E Bio? Egra? Acid? E Fertilizers: the formation of fertilizers can be defined as the? Catalanic? Acid acidity and the conversion of organic wastes into fertilizer. One of the key features of fertilizer piles is that they can be self-heating; heat is a natural by-product of the metallical breakdown of organic matter. Depending on the size of the stack, c your ability? for ais-laraee, the heat can be trapped and probocar that the internal temperature rises. The "efficient" acidity that enters the piles of fertilizer will cause a natural progression or succession to occur in the micronic population. Initially, the micronic population - the fertilizer is outstanding for its mesophilic species (the temperatures for optimal growth vary between 20 and 45 ° C). The process begins with the proliferation of the natural roe-sofilica microflora and the metabolism of organic matter. This result in the production of large amounts of heat, which reaches the temperatures of the internal battery between 55 to 65 ° C. The higher temperature acts as a selective pressure favoring the growth of the thermophilic species by one side (the range of dptical growth is between 45-60 ° C), while inhibiting the mesdfilos, on the other the? .
