An elastomeric article having a rubber component comprising polyisoprene and an aldehyde aniline condensate, the elastomeric article having less than 1 ppm diisopropyl xanthogen polysulfide residue.

Vulcanization composition for reducing allergenic potential and elastomeric articles formed therewith

This invention relates generally to vulcanization compounds and relates more specifically to vulcanization compositions with reduced allergenic potential that include accelerator compositions for vulcanizing elastomeric articles. Vulcanization compositions are disclosed that include a single fugitive dihydrocarbyl xanthogen polysulfide accelerator and a single aldehyde-aniline condensate accelerator.

The present invention is directed to antistatic elastomeric articles and methods of making the same. The articles can be single layered or multilayered. The single layered articles possess desirable antistatic properties and desirable properties of comfort and feel. The multilayered articles have an outermost layer/surface that possesses desirable antistatic properties and an innermost layer/surface that exhibits desirable properties of comfort and feel. In preferred embodiments, the elastomeric articles are made form a nitrile/natural rubber blend. Articles of the present invention have antistatic properties measured as having a surface resistivity below about 10&#x3a9;/sq and a static decay time of less than about 60 seconds.

Antistatic gloves and process for making same

An aqueous elastomer dispersion includes a dispersed phase and an aqueous phase. The dispersed phase includes an elastomer including curable aliphatic conjugated-diene elastomers, such as polyisoprene, and a minor amount of at least one additive. The aqueous phase includes water and other optional components in either a soluble state or a dispersion state. The aqueous elastomer dispersion may be prepared by dissolving an elastomer, such as rubber, and additives in a solvent mixture and then converting the resulting solution into an aqueous emulsion. The aqueous emulsion is concentrated and the solvent is stripped from it to yield a dilute latex. The dilute latex that is obtained is concentrated again. Articles made from the aqueous elastomer dispersion include medical gloves, condoms, probe covers, dental dams, finger cots, catheters and the like.

Water-based resin composition and articles made therefrom

Methods for preparing copolymeric emulsions from at least one water soluble monomer and at least one water insoluble monomer are disclosed herein. In some embodiments, one or more surfactants and stabilizers may be used. In some embodiments, the monomers used in the process include, by total monomer weight, at least 50% water soluble monomers and at least 10% water insoluble monomers. Copolymer emulsions formed from the reaction product of at least one water soluble monomer and at least one water insoluble monomer are also disclosed along with articles coated with such emulsions and coating formulations made from such emulsions as well as methods for the manufacture and coating of such articles.

Hydrophilic/hydrophobic aqueous polymer emulsions and products and methods relating thereto

This invention relates to an elastomeric article with improved lubricity and donnablity and reduced stickiness/tackiness. According to the methods of the invention, the internal surface of the elastomeric article is coated with a polyisoprene coating. The coating of the invention is formed from synthetic polyisoprene rubber that may or may not contain minor amounts of other components. The coating is preferably directly bonded to the underlying elastomeric article.

Glove coating and manufacturing process

The present invention relates generally to methods of sterilizing elastomeric articles in a manner that prevents and/or reduces degradation to the articles, particularly degradation that may be caused and/or accelerated by sterilization techniques such as gamma irradiation, x-ray irradiation, and electron-beam processing. The methods include packaging the elastomeric articles in order to improve their resistance to degradation. In certain aspects of the invention, packaged elastomeric articles, optionally containing one or more antidegradants, such as antioxidant and/or antiozonant compounds, are also provided. The methods of providing degradation-resistant elastomeric articles in accordance with the present invention may also be used to reduce the occurrence of cracking and discoloration in elastomeric articles, regardless of whether they are subjected to sterilization.

Methods for packaging and sterilizing elastomeric articles and packaged elastomeric articles produced thereby

The present invention generally relates to vulcanization compositions used to vulcanize elastomeric articles, where the vulcanization compositions have reduced allergenic potential as compared to elastomeric articles formed using vulcanization compositions having non-fugitive accelerators. The present invention also relates to elastomeric articles formed using the vulcanization compositions. The invention further relates to methods for making a reduced-allergenicity vulcanization composition, and to methods for using the vulcanization compositions to vulcanize elastomeric articles.

Vulcanization composition having reduced allergenic potential, and elastomeric articles formed therewith

Described are systems, devices, and methods for stripping a formed thin film elastomeric article such as a latex or synthetic polymer medical or surgical glove from a mold, inverting the article, and transferring and securing the inverted article to a mandrel for further on-line processing, integrating dip forming and off-line surface treatment processes into a single, continuous on-line process. The system can include a stripping apparatus including an actuation device for peeling the article from the mold and inverting the article, and a donning device to receive the inverted article. The system may position the article about a mandrel of the donning device. The mandrel may expand or separate to engage the interior of the inverted article to securely hold the article on the mandrel. The donning device may be coupled to a continuous loop conveyor chain to carry the donning device and the mounted article through on-line secondary processing.
