Articles of protective wear are normally designed to protect a wearer against one or one group of hazardous materials such as chemical warfare agents. Such chemical warfare protective wear is normally made out of a butyl rubber as butyl rubber provides favorable impermeation protection against a wide variety of both chemical and biological warfare agents while having excellent physical properties. However, the protection provided by butyl rubber based protective wear is seriously reduced when exposed to hydrocarbons as the butyl rubber based protective wears' impermeation integrity is severely impaired. This problem is solved by using an article of protective wear which has a multilayer/multipolymer configuration so that enhanced protection against more than one type of material, such as hydrocarbons and chemical warfare agents, is provided. More specifically, the article has a first layer comprising a hydrocarbon resistant resin and a second layer having a resin modified butyl rubber layer, the butyl rubber base being characterized in having crosslinks formed by a resin rather than by sulphur or sulphur bearing materials. Also included is a method of formation of such articles.
