摘要：
An extrudable elastomeric composition includes an elastomeric polymer and a tackifying resin in which the extrudable elastomeric composition is adapted to form an elastic sheet having a stress relaxation of less than about 30 percent. The elastomeric polymer is a styrene-poly(ethylene-propylene)-styrene thermoplastic elastomeric block copolymer or a mixture of styrene-poly(ethylene-propylene)-styrene and styrene-poly(ethylene-butylene)-styrene elastomeric block copolymers. The extrudable elastomeric composition may also include a polyolefin and/or an extending oil.
