GASKET-FORMING SOLVENT-BASED COMPOSITIONS CONTAINING STYRENE-BUTADIENE BLOCK COPOLYMERS

摘要

Gasket-forming compositions based on styrene-butadiene block copolymers blended with a minor portion of random styrene-butadiene copolymer and polyisobutylene are prepared by conventional rubber compounding techniques in the presence of low molecular weight polyethyethylene. Fillers and solvents are used to complete the formula.
