Abstract

Provided are multilayer elastomer compositions such as multilayer films which possess the ability to self-repair upon puncturing. The multilayer elastomer compositions may be prepared from, for example, styrenic block copolymers and find use in the manufacture of thin walled articles, for example gloves, particularly medical or industrial gloves.

Abstract

Provided are multilayer synthetic rubber compositions formed from a layer of a styrene block copolymer composition and a layer of one or more synthetic elastomers, such as polychloroprene, polyisoprene, nitrile rubber, styrene butadiene rubber, butyl rubber and polyurethane. The multilayer compositions find use in the manufacture of thin walled articles, for example gloves, particularly medical or industrial gloves.

Abstract

Provided are radiation-attenuating compositions formed from mixtures of structural polymers, plasticizers and radiopaque substances. The compositions can be formed into thin films which find use in the manufacture of gloves, particularly gloves for medical use. The gloves have advantageous properties in terms of flexibility and comfort and provide sufficient and consistent attenuation of X-rays.
