- a combination of precursor acid copolymers including a dipolymer and a terpolymer may be suitable.
- the precursor acid copolymer may have a melt flow rate (MFR) of about 10 to about 4000 g/10 min, about 10 to about 2500 g/ 10 min, about 10 to about 1400 g/10 min, about 35 to about 1200 g/10 min, about 70 to about 1000 g/10 min, about 100 to about 500 g/10 min, or about 200 to about 500 g/10 min, as determined in accordance with ASTM method D1238 at 19O 0 C and under a weight of 2.16 kg.
- MFR melt flow rate
- the precursor acid copolymers may be synthesized in a continuous process in which each of the reactive comonomers and the solvent or solvents, if any, are continuously fed, together with initiator, into a stirred reactor.
- the choice of initiator is based on the anticipated reactor temperature range coupled with the decomposition temperature of the initiator, the criteria for this selection being well-understood in the industry.
- the reaction temperature may be maintained at about 12O 0 C to about 300 0 C, or about 14O 0 C to about 26O 0 C.
- the pressure in the reactor may be maintained at about 130 to about 310 MPa, or about 165 to 250 MPa.
- the reactor may be, for example, an autoclave such as those described in U.S. Patent No. 2,897,183. Specifically, U.S. Patent No.
- 2,897,183 describes a type of autoclave that is equipped with means for intensive agitation. It also describes a continuous process for the polymerization of ethylene under a "substantially constant environment.” This environment is maintained by keeping certain parameters, for example, pressure, temperature, initiator concentration and the ratio of polymer product to unreacted ethylene, substantially constant during the polymerization reaction. Such conditions may be achieved in any of a variety of continuously stirred tank reactors, among them, for example, continuously stirred isothermal reactors and continuously stirred adiabatic reactors.
- the reaction mixture which contains the ethylene copolymer product, is vigorously agitated and continuously removed from the autoclave. After the reaction mixture leaves the reaction vessel, the resulting ethylene copolymer product is separated from the volatile unreacted monomers and solvents, if any, by conventional procedures, such as by vaporizing the unpolymehzed materials and solvents under reduced pressure or at an elevated temperature.
- the reactor contents should be maintained under conditions such that a single phase is present substantially throughout the reactor. This can be accomplished by adjusting reactor temperature, by adjusting reactor pressure, by addition of co-solvents, or by any combination of these techniques, as described in U.S. Patent No. 5,028,674. Conventional means may be used to determine whether a single phase is maintained substantially throughout the reactor. For example, Hasch et al., in
- the precursor acid copolymers are neutralized with a base so that the carboxylic acid groups in the precursor acid copolymer react to form carboxylate groups.
- the precursor acid copolymers groups are neutralized to a level of about 20 to about 90 %, or about 30% to about 90%, or about 35% to about 90%, or about 40% to about 90%, or about 40% to about 70%, or about 43% to about 60%, based on the total carboxylic acid content of the precursor acid copolymers as calculated or as measured for the non-neutralized precursor acid copolymers.
- any stable cation and any combination of two or more stable cations are believed to be suitable as counterions to the carboxylate groups in the ionomer.
- Divalent and monovalent cations such as cations of alkali metals, alkaline earth metals, and some transition metals, are preferred.
- Zinc is a preferred divalent cation.
- Monovalent cations are more preferred.
- the base is a sodium ion-containing base, to provide a sodium ionomer wherein about 40% to about 90%, or about 40% to about 70%, or about 43% to about 60% of the hydrogen atoms of the carboxylic acid groups of the precursor acid are replaced by sodium cations.
- the precursor acid copolymers may be neutralized by any conventional procedure, such as those described in U.S. Patent Nos. 3,404,134 and 6,518,365.
- the as-neutralized sodium ionomer may have a MFR of about 0.7 to about 25 g/10 min or less, or about 0.7 to about 19 g/10 min or less, or about 1 to about 10 g/10 min, or about 1.5 to about 5 g/10 min, or about 2 to about 4 g/10 min, as determined in accordance with ASTM method D1238 at 19O 0 C and 2.16 kg.
- the as- neutralized sodium ionomer may have a freeze enthalpy that is not detectable or less than about 3 j/g, or less than about 2 j/g, as determined by differential scanning calohmetry (DSC) in accordance with ASTM method D3418 when using a DSC apparatus manufactured by Mettler or by TA (for example the Universal V3.9A model).
- DSC differential scanning calohmetry
- the peak height may be very small and the peak width at half height may be relatively great, so that a broad peak having a small integral area may not be detectable or discernable when a baseline is subtracted from the DSC trace. In general, when ASTM D3418 is followed, a freeze enthalpy that falls below 0.2 j/g is not detectable.

- the ionomer compositions may contain any effective amount of thermal stabilizer(s). Use of a thermal stabilizer is optional and in some instances is not preferred. When one or more thermal stabilizers are used, they may be present in the ionomer compositions at a level of at least about 0.05 wt%, and up to about 10 wt%, more preferably up to about 5 wt%, and still more preferably up to about 1 wt%, based on the total weight of the ionomer composition.
- UV absorbers can be used and have also been widely described in the art. Any known UV absorber may find utility in the ionomer compositions described herein. Preferred classes of UV absorbers include, but are not limited to, benzotriazoles, hydroxybenzophenones, hydroxyphenyl triazines, esters of substituted and unsubstituted benzoic acids, and the like and combinations of two or more thereof.
- the ionomer compositions may contain any effective amount of one or more UV absorbers. Use of an UV absorber is optional and in some instances is not preferred.
- UV absorber(s) When UV absorber(s) are used, they may be present in the ionomer compositions at a level of at least about 0.05 wt%, and up about 10 wt%, more preferably up to about 5 wt%, and still more preferably up to about 1 wt%, based on the total weight of the ionomer composition.
- Hindered amine light stabilizers can be used and have also been widely described in the art.
- hindered amine light stabilizers are secondary or tertiary, acetylated, N hydrocarbyloxy-substituted, hydroxyl- substituted, N-hydrocarbyloxy substituted, or other substituted cyclic amines which further incorporate steric hindrance, generally derived from aliphatic substitution on the carbon atoms adjacent to the amine function.
- the ionomer compositions may contain any effective amount of one or more hindered amine light stabilizers. Use of hindered amine light stabilizers is optional and in some instances is not preferred.
- hindered amine light stabilizer(s) When hindered amine light stabilizer(s) are used, they may be present in the ionomer compositions at a level of at least about 0.05 wt%, and up to about 10 wt%, more preferably up to about 5 wt%, and still more preferably up to about 1 wt%, based on the total weight of the ionomer composition.
- articles comprising the ionomer compositions described herein.
- Articles comprising or made from these ionomer compositions exhibit equal or better optical properties (e.g., equal or lower haze as determined in accordance with ASTM D1003) than those made from prior art ionomers.
- the improved optical properties are not affected by the cooling rate that follows the process of fabricating the article.
- the ionomer compositions described herein are thermoplastic. Accordingly, articles comprising these compositions are most often formed by processes that include the step of melting the ionomer and the other components of the ionomer composition, and the step of shaping the desired article from the polymer melt.
- thicker articles may be cooled to room temperature at a slower rate due to the limitations of heat transfer or due to economic limitations that prevent the use of expensive cooling equipment. In general, however, a slow cooling rate is unfavorable for the optical properties of ionomers.
- ethylene acid copolymers and their ionomers may have a high degree of inhomogeneity (non-randomness or "blockiness") in the comonomer distribution along the length of the polymer chain. The result is that these materials include long stretches of consecutively copolymerized ethylene residues that are capable of organization into crystals, just as polyethylene itself has a well-known tendency to crystallize.
- the ionomer compositions described herein have good optical properties, even when cooled at very low rates.
- the exceptionally small or even unmeasurable freeze enthalpies of the ionomers described herein are evidence that these ionomers have no tendency, an insignificant tendency, or a very low tendency towards crystallization. Again without wishing to be held to theory, it is believed that this favorable tendency is the result of a higher degree of homogeneity (that is, randomness or "non- blockiness") in the comonomer distribution along the length of the polymer chain of the ionomers described herein.

- Patent 5,028,674 by controlling the ratio of ethylene to methacrylic acid and the flow rate of the initiator, the reactor conditions were maintained at a temperature of about 200 0 C to about 26O 0 C and at a pressure of between 170 and 240 MPa; (2) no propane telogen was fed in the reactor (except in CE13); (3) the total concentration of methanol in the reactor was maintained at about 2 to 5 mol%, based on the total feed of ethylene, methacrylic acid, methanol and initiator solution (or based on the total feed of propane telogen, ethylene, methacrylic acid, methanol, and initiator solution in CE13); and (4) the system was maintained at a steady state with the residence time of the material flowing through the reactor being about 5 seconds to 2 minutes.
- tert-butyl peracetate In addition, depending on the particular acid copolymer to be synthesized, one of two different free-radical initiators were used, tert-butyl peracetate or tert-butyl peroctoate.
- te/t-butyl peracetate was the initiator (as in Examples E1 , E2, E3, CE1 , CE2, CE3, CE13, and CE15)
- tert-butyl peroctoate was the initiator (as in Comparative Examples CE4, CE5, CE6, CE7, CE8, CE9, CE10, CE11 , CE12, CE14, and CE16), it was utilized as a mixture at 90% concentration in odorless mineral spirits.
- the ionomers were obtained by partially neutralizing the precursor copolymers of ethylene and methacrylic acid with sodium hydroxide solution, either in a single screw extruder under high shear melt mixing conditions with the melt temperature set at 200 0 C to 27O 0 C, or using the general method described in Example 1 of U.S. Patent No. 6,518,365.
- the as-obtained ionomers then underwent differential scanning calohmetry (DSC) testing in accordance with ASTM D3418 with a temperature profile of (a) heating to 18O 0 C; (b) holding for 3 minutes; (c) cooling to 25 0 C at a rate of 10°C/min; (d) holding for 3 minutes; and (e) heating to 18O 0 C at a rate of 10°C/min.
- DSC differential scanning calohmetry
- melt flow rate (MFR) of the precursor acid copolymer was calculated based on the MFR of the ionomer
- % neut. Sodium is the percentage of carboxylic acid groups present in the precursor acid copolymer which have been neutralized
- melt flow rate (MFR) of the ionomer as determined in accordance with ASTM D1238 at 19O 0 C and 2.16 kg;
- freeze enthalpy is not detectable, when measured in accordance with ASTM D3418-03.
- the ionomers were fed into 25 mm diameter Killion extruders under the temperature profile set forth in Table 2 and extrusion cast into polymer sheets.
- the polymer throughput was controlled by adjusting the screw speed to maximum throughput, a 150 mm slot die with a nominal gap of 2 mm was fed by the extruder, the cast sheet was fed onto a 200 mm diameter polished chrome chill roll held at a temperature of between 10 0 C and 15°C and rotating at 1 to 2 rpm.
- the nominally 0.76 mm (30 mil) thick sheets were then removed and cut into 300x300 mm squares.
- the ionomer sheets were used as interlayer sheets to form glass laminates. Specifically, annealed glass sheets (100x100x3 mm) were washed with a solution of trisodium phosphate (5 g/l) in de-ionized water at 5O 0 C for 5 min, then rinsed thoroughly with de-ionized water and dried. Six sheets of each ionomer (about 0.76 mm thick) were stacked together and placed between the two lites of glass sheet to form a pre-lamination assembly having an interlayer with a total thickness of about 180 mils (4.57 mm). The moisture level of the ionomer sheets was kept below 0.06 wt% by minimizing their exposure to ambient conditions (-35% RH). The pre-lamination assembly was stabilized by the application of polyester tape in several locations to maintain relative positioning of each layer with the glass lites. A nylon fabric strip was placed around the periphery of the assembly to facilitate air removal from within the layers.
- the pre-lamination assembly was placed inside a nylon vacuum bag and sealed. A connection was made to a vacuum pump, and the air within the bagged assembly was substantially removed by reducing the air pressure inside the bag to below 50 millibar absolute. The bagged assembly was then heated in a convection air oven to 12O 0 C and maintained at these conditions for 30 min. A cooling fan was used to cool the assembly to near ambient temperature, after which the vacuum source was disconnected and the bag was removed, yielding a fully pre-pressed assembly of glass and interlayer. Although hermetically sealed around the periphery, several areas of the assembly were not fully bonded as indicated by the presence of bubbles in these areas.
- the pre-pressed assembly was placed into an air autoclave and the temperature and pressure were increased from ambient to 135 0 C and 13.8 bar over 15 min. The assembly was maintained at these conditions for 30 min, after which the resulting laminate was "fast cooled” (i.e., at Cooling Rate A of 2.5°C/min) to room temperature at ambient pressure.
- the as-obtained laminate was tested for haze in accordance with ASTM D1003 using a Haze- gard Plus hazemeter (BYK-Gardner, Columbia, MD).
- the haze levels of glass laminates comprising prior art ionomer interlayer sheets are dependent on the cooling rate under which the laminates were obtained. In general, slower cooling rates increase the laminates' haze. As illustrated by Table 1 , however, glass laminates comprising interlayer sheets made from the ionomers described herein (Examples E1 to E3) tend to have lower haze than those comprising prior art ionomer interlayer sheets (Comparative Examples CE1 to CE16). Moreover, the haze levels of laminates of Examples E1 to E3 were not affected by the cooling rate under which the laminates were obtained.
- Example E4 and Comparative Example CE17 In Example E4 and Comparative Example CE17, the ionomers used in Example E4 and Comparative Example CE17, the ionomers used in Example E4 and Comparative Example CE17, the ionomers used in Example E4 and Comparative Example CE17, the ionomers used in Example E4 and Comparative Example CE17, the ionomers used in Example E4 and Comparative Example CE17, the ionomers used in
- Example E3 and Comparative Example CE2, respectively, were injection molded into rectangular test bars with the dimension of 125x75x3 mm (thin test bars) or 125x45x20 mm (thick test bars) as follows.
- the resins were fed into a Model 150-6 HPM injection molding machine (Taylor's Industrial Services, Mount Gilead, OH).
- the ionomer melt temperature was in the range of 13O 0 C to 200 0 C and the mold temperature was maintained at a temperature of about 1 O 0 C.
- the mold cycle time was approximately 90 seconds.
- These "air-cooled" test bars were obtained by ejecting the molded bars from the mold and allowing the molded bars to cool to room temperature (about 22+3 0 C) under ambient conditions.
- FIG. 1 shows the results of Comparative Example CE18. Specifically, FIG. 1 is the DSC trace of a prior art ionomer, clearly showing peaks corresponding to heat flow in and out of the ionomer sample. Integration of these peaks provides the freezing enthalpy or crystallization energy of the material.
- FIG. 2 shows the results of Example E5; specifically, it is the DSC trace of a sodium ionomer described herein. In contrast to the results shown in FIG. 1 , the DSC trace in FIG. 2 shows that the sodium ionomer described herein has an insignificantly small or undetectable freezing enthalpy.
