Beschreibung
Zusammenfassung:	An adhesive composition is provided for adhering together roofing materials such as EPDM rubber and thermoplastic polyolefin (TPO). The adhesive composition includes a rubbery polymer comprising a blend of a thermoplastic block copolymer selected from the group consisting of a styrene-butadiene-styrene block copolymer, a styrene-isoprene-styrene block copolymer, a styrene-ethylenelbutylene-styrene block copolymer, a styrene-ethylene/propylene block copolymer and an ethylene-propylene block copolymer and combinations thereof and a polyisobutylene. Roofing articles incorporating the adhesive composition are also provided. The composition is a pressure sensitive adhesive that allows roofing articles to be applied in a peel and stick manner.
