An elastomeric breathable three-dimensional composite material and the process for producing the same are disclosed. A carrier material is supplied onto a top surface of continuous portions of an elastomeric film to form the composite material. A pressure differential is applied to a bottom surface of film for a period of time sufficient for three-dimensional apertured structures to be formed in the film.

The present invention relates to a removable and/or reactivatable, transparent pressure sensitive adhesive obtainable by polymerizing a precursor comprising a monomer component which contains one or more alkyl acrylates, the alkyl groups of which have an average of 4-14C atoms, and which is essentially free from polar comonomers, said precursor further comprising at least about 2.0 phr of hydrophobic silica, one or more polymerization initiators and one or more crosslinker compounds in a concentration resulting in a crosslink density obtainable by using tripropyleneglycoldiacrylate as a reference crosslinker compound in a concentration of 0.15 phr or more.

Powder-free natural rubber and synthetic elastomeric articles, in particular, gloves, having an inner coating of a nitrile rubber with an intermediate layer of a rubber blend comprised of natural or synthetic rubber and nitrile rubber interposed between the nitrile coating and the base glove and their method of manufacture are described. The intermediate layer of the rubber blend interposed between the coating and the glove imparts a unique surface texture to the glove which aids donning and eliminates self-sticking of the inner glove surfaces, especially after the glove has been sterilized by radiation. Additionally the gloves of the invention exhibit good grippability, good donnability, superior tensile strength, elongation to break and stress at 500% elongation.

An elastomeric material and gloves made therewith are substantially impermeable to water vapor and liquid water, have a relatively high tensile strength, and have a relatively low resilience. The gloves conform to the shape of a hand when stretched to fit about the hand and then relax so that the pressure exerted on the hand is substantially reduced. The gloves are particularly useful in medical applications and most particularly useful as surgical gloves.

N-halamine biocidal materials and coatings are provided. Monomeric oxazolidinones or hydantoins are homopolymerized or copolymerized with other monomers so as to produce materials or coatings, which upon exposure to solutions of chlorine or bromine become biocidal. The biocidal materials and coatings are effective at inactivating microorganisms upon surface contact and are regenerable following loss of efficacy upon further exposure to solutions of chlorine or bromine. Surfaces which could be treated with the materials and coatings include, but are not limited to: glass, plastic, metals, fibers, and wood for use in pool and tank liners, food wrappers, catheters, paints, tiles, shower walls, fabrics, sterile bandages, pipes, medical and dental coatings, preservatives, and the like.

Surface active N-halamine compounds

A latex film product such as a prophylactic condom, a surgical glove, a medical examination glove, and the like, having improved chemical resistance, such product comprising a shaped film consisting essentially of a cured mixture of a) a copolymer of acrylonitrile and butadiene or isoprene, and b) a high styrene content styrene-butadiene copolymer

Elastomeric film products with improved chemical resistance

Natural rubber latex compounds are modified by the addition of a high styrene content styrene-butadiene copolymer. The films prepared from these modified NR latex compositions exhibit improved tear strength and a good balance of other properties.

A process for drawing, with plug assist, thin walled, closed-ended, tubular articles of thermoplastic elastomer is disclosed as well as a thermoplastic elastomer and apparatus therefor. According to the process, a plug, extensible into the mold cavity, is employed concurrently with a varying air pressure differential across the faces of the preform to bias the flow of the drawn article axially along the length of the tubular mold and away from the mold walls. At a point where the article is drawn substantially the length of the tubular mold, the mold is evacuated and the article finally formed against the mold walls. Such articles are usefully employed as condoms or finger cots.
