Description

ELASTOMERIC MATERIAL FOR RUBBER ARTICLES FIELD OF THE INVENTION The invention relates to latex polymer compositions useful for making rubber articles. More specifically, the invention relates to latex polymer compositions that are capable of forming materials possessing a combination of physical properties.

BACKGROUND OF THE INVENTION Rubber articles such as gloves, condoms, bags, and the like are formed of latex polymeric materials and are useful in a wide variety of applications related to for example medical, industrial, and home uses. These polymeric materials are generally water-based polymers that are easily formed using commercially known methods. In such procedures, it is important that the latex material be able to form a film on the surface of a mold. An example of such use relates to the manufacture of latex gloves, especially for medical applications. Latex gloves are preferred because they can be made lightweight, thin, flexible, tight, and substantially impervious to a variety of liquids and gases. It is often desirable for gloves to have _ ^^^ rt ^ W ^ fa ^ j | ^ hm ^^^^ _ ^ - rí? ^^^^^ jgf ^? m ^ v * mtnr? &amp? mA? ae1l * tr *. suitable physical properties such as resistance to tension and elongation, and are comfortable for the user. It is also desirable that the gloves possess adequate aesthetic properties with respect to creasing, softness, etc., which provide a good barrier to microbial penetration, and are substantially odorless. A combination of high tensile strength and elongation combined with a low modulus is typically preferred. In addition to the above, it is desirable that the glove have sufficient elastic flexibility or recovery. Conventional latex gloves have been formed typically of natural rubber mainly due to its flexibility, softness, adequate physical properties, and good elastic recovery. However, many users of such gloves are allergic to the proteins found in natural gum. These individuals often experience difficulty when using gloves. As a result, they have been efforts to develop gloves made from synthetic materials that are comparable to natural rubber gloves in terms of comfort and physical properties. A synthetic alternative focuses on the use of polyvinyl chloride (PVC). PVC is typically plasticized in order to be flexible enough to be used in applications of gloves The gloves formed from PVC are undesirable in many aspects. For example, gloves do not have the feeling of softness and sliding. In addition, the plasticizer can migrate through the PVC and leach when in contact with solvents. In addition, it is believed that Synthetic gloves formed from vinyl materials can provide an insufficient barrier to microbes due to imperfections in the film. Additionally, these gloves tend to exhibit inadequate properties of elastic recovery (flexibility) and poor smoothness. Another possible alternative to gloves made of natural rubber is described in U.S.A. No. 5,014,362 to Tillotson et al. The Tillotson et al patent proposes gloves made of elastomeric material which allegedly possess adequate physical properties in relation to fluid permeability, strength, and flexibility. It is taught that the gloves are formed from a rubber containing nitrile, more particularly a carboxylated nitrile rubber containing butadiene. Nitrile-containing rubber gloves are typically desirable in very demanding end-use applications, such as those that often require superior properties such as resistance to solvent and pitting. Nevertheless, for more general, less demanding applications, it is often not necessary for the gloves to exhibit such properties. Rubber gloves containing nitrile also often exhibit inferior properties of flexibility and softness. A need in the art remains for a synthetic latex material suitable for forming rubber articles such as gloves which are free of natural rubber proteins and which can provide an adequate barrier to microbial penetration. The articles must also possess a broad scale of desirable physical properties in relation to strength, elongation and modulus, as well as providing adequate aesthetic properties, in relation to, for example, crease. It is highly desirable that the articles possess improved properties with respect to elastic recovery (elasticity) and softness. In addition, it would be desirable to be able to manufacture the synthetic latex articles by existing commercial processes.

BRIEF DESCRIPTION OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide a latex polymer suitable for forming rubber articles which is free of natural rubber proteins and imparts desirable physical properties to the articles made therefrom. It is also an object of the invention to provide a latex polymer suitable for forming rubber articles which is free of natural rubber proteins and possesses good aesthetic properties in relation to, for example, creasing. It is a further object of the present invention to provide a latex polymer suitable for forming rubber articles having properties of improved softness and elastic recovery (elasticity). It is yet another object of the present invention to provide latex polymer compositions used in rubber articles which can be formed using existing commercial procedures.

For these and other purposes, in one aspect, the present invention provides a latex polymer composition suitable for manufacturing rubber articles. The composition consists of 80 to 99% by weight of a conjugated diene monomer; from 0 to 10% by weight of an unsaturated acid monomer, and from 0 to 20% by weight of an additional unsaturated monomer. The latex polymer composition has a glass transition temperature of no greater than -50 ° C. The percentages by weight are based on the total weight of the monomers. A preferred diene monomer conjugate is 1,3-butadiene. A preferred unsaturated acid monomer is methacrylic acid. In another aspect, the invention provides an interlaced film formed from a latex polymer composition. Preferably, the interlaced film has a tensile strength of at least 70.31 kg / cm2, an elongation of at least 600%, and a modulus at 100% elongation of no more than 21.093 kg / cm2. In still another aspect, the invention provides a glove formed from the latex polymer composition of the invention. Preferably, the glove has a tensile strength of at least 70.31 kg / cm2, an elongation of at least 600%, and a modulus at 100% elongation of no more than 21.093 kg / cm2.

According to the invention, the latex polymer composition may also include an additional unsaturated monomer. The additional unsaturated monomer can be used for several reasons. For example, the additional unsaturated monomer may aid in the processing, more specifically, help to reduce the polymerization time of the latex. The presence of the additional unsaturated monomer can also help to improve the physical properties of a film, glove, or other article containing the latex polymer composition. A number of unsaturated monomers can be used and are well known to the person skilled in the art. Examples include, but are not limited to, ester monomers, nitrogen-containing monomers, and aromatic monomers. Mixtures of the above can be used. In addition to the scale described herein, the additional unsaturated monomer can be used from 5 to 15 based on the weight of the monomers. The ester monomers that can be used are well known and include, for example, acrylates and methacrylates. The acrylates and methacrylates can include functional groups such as amino groups, hydroxy groups, epoxy groups and the like. Exemplary acrylates and methacrylates include monocarboxylic ester monomers such as, but not limited to, methyl acrylate, methyl methacrylate, ethyl acrylate, ethyl methacrylate, butyl acrylate, butyl methacrylate, 2-ethylexyl acrylate, glycidyl acrylate. , glycidyl methacrylate, hydroxyethyl acrylate, hydroxyethyl methacrylate, hydroxypropyl acrylate, hydroxypropyl methacrylate, isobutyl methacrylate, hydroxybutyl acrylate, hydroxybutyl methacrylate, 3-chloro-2-hydroxybutyl methacrylate, n-propyl methacrylate, and Similar.

Specific monomers include diethyl and dimethyl fumarates, itaconates and maleates. Other suitable ester monomers include di (ethyleneglycol) maleate, di (ethyleneglycol) itaconate, bis (2-hydroxyethyl) maleate, 2-hydroxyethylmethyl fumarate, and the like. The monomers of mono and dicarboxylic acid esters can be mixed or copolymerized with one another. Ester monomers that can be used in latex polymer compositions also include, for example, partial esters of unsaturated polycarboxylic acid monomers. These monomers typically include di- or higher-unsaturated acid monomers in which at least one of the carboxylic groups is esterified. An example of this class of momomeres is of the formula ROOC-CH = CH-COOH in which R is an alkyl group of C-i to C.2, for example monomethyl maleate, monobutyl maleate and monooctyl maleate. Medium itaconic acid esters having C. to C.2 alkyl groups such as monomethyl itaconate may also be used. Other monoesters, such as those in which R in the above formula is an oxyalkylene chain instead of alkyl may also be used. Mixtures or copolymers of the partial ester of the unsaturated polycarboxylic acid monomer can also be used. The nitrogen-containing monomers that can be used include, for example, acrylamide, N-methiolacrylamide, N-methylo methacrylamide, methacrylamide, N-isopropylacrylamide, -tert-butylacrylamide, N-N'-methylene-bis-acrylamide.; N-methylolacrylamides alkylated as N-methoxymethylacrylamide and N-butoxymethylacrylamide; acrylonitrile and methacrylonitrile.

For example, the aionic surfactants can be selected from a broad class of sulfonates, sulfates, ether sulphates, sulfosuccinates and the like, the choice of which will be apparent to one skilled in the art. Nonionic surfactants can also be used to improve film and glove characteristics, and can be selected from the alkylphenoxypoly- (ethyleneneoxy) ethanols family wherein the alkyl group typically varies from C7-C.8 and the oxide units of ethylene vary from 4-100 moles.

More preferably, the chain transfer agent is used from 0.3 to 1.5% by weight, and more preferably from 0.3 to 1.0% by weight.

The monomers used in the formation of the latex polymer composition of the invention can be polymerized in a manner known to those skilled in the art. For example, the monomers can be polymerized at a temperature preferably between 5 ° C and 95 ° C, and more preferably 10 ° C and 70 ° C. The invention also relates to an interlaced film formed from a latex polymer composition described herein. Numerous articles of manufacture can be formed from the interlaced film and the latex polymer composition according to the process of the invention. Such latex articles generally include those that are typically made from natural rubber and which contact the human body. Illustrative articles of manufacture include, but are not limited to, gloves, condoms, medical devices, catheter tubes, balloons, and blood pressure bags. Illustrative techniques are described in U.S. Patent No. 5,084,514 to Szczechura et al., The disclosure of which is incorporated by reference herein in its entirety. Typically, the latex polymer composition is composed of one or more crosslinkers (eg, metal oxide such as zinc oxide, sulfur, and peroxides), together with antioxidants, fillers, and other ingredients. The formation of composition or mixture can be done in any suitable way. Suitable shapes or molds in the form of a hand are heated in an oven, and then submerged or sinked in a coagulant. A suitable coagulant includes, for example, a solution of a metal salt, preferably calcium nitrate, in water or alcohol. The form is removed after the coagulant, and the excess liquid is allowed to dry. As a result, a residual coating of coagulant is left on the form. The form coated with the coagulant is then submerged or sunk in the latex polymer composition of the present invention. The latex coagulates and forms a film on the shape. The amount of time that the form is submerged in the latex typically depends on the thickness of the movie. As long as I spend more time, the movie is thicker. The form is removed after the latex, and immersed in a water bath to remove the coagulant and some of the surfactant. The coated form of the latex is then placed in a drying oven at a temperature preferably between 60 ° C and 100 ° C to remove water from the film. When the film is dry, the mold is placed in a curing oven preferably at a temperature between 100 ° C and 170 ° C for 5 to 30 minutes. If desired, the same oven can be used for drying and curing, and the temperature can increase over time. The cured glove is removed from the shape. It can be powdered or post-processed for ease of removal and for ease of training. The glove preferably has a thickness on the scale of 3 thousand to 20 thousand. The interlaced film and the glove formed in accordance with the present invention may have various physical properties. Preferably, w the above materials have a tensile strength of at least 70.31 k / cm2, an elongation of at least 600%, and a modulus at 100% elongation of no more than 21,093 k / cm2. More preferably, the materials have a tensile strength of 105.45 k / cm2, an elongation of at least 650%, and a modulus at 100% elongation of no more than 17.57 k / cm2. In addition to the above, the interlaced film and the glove produced according to the invention may contain additional (at least a second) polymeric films in contact therewith so as to form composite body structures. The application of additional polymeric films can be achieved by techniques that are known in the art. For example, polymer films can be formed on the film and glove interlaced by coating, aspersion, or "over-immersion". The resulting materials can be dried and cured according to known and accepted techniques. Additional polymeric films can be formed from a wide number of materials including, but not limited to, neoprene, nitriles, urethanes, acrylics, polybutadiene, polyisopropene, and the like. Mixtures of the above can also be used. Additional polymeric films may be present in a variety of configurations. For example, in one embodiment, an additional film may be placed above the interlaced film. In a second embodiment, an additional film may be placed below the interlaced film. In a third embodiment, the interlaced film may be idealized between two additional films. The different film configurations can be selected as desired by the person skilled in the art. The interlaced film of the invention can be used in conjunction with other conventional materials, such as textile substrate which may be present in the form of an article such as a glove, for example. As an example, support gloves are well known in the art. In this instance, the interlaced film typically covers the textile substrate, although other configurations are possible. For objects of the invention, the term "textile" should be interpreted broadly and may be formed from a variety of polymeric and natural materials such as, but not limited to, nylon, polyester, and cotton. Mixtures and combinations thereof can also be used. The following examples are merely illustrative of the invention and are not limiting thereof.
