Abstract:
A composition having a compression set at 100Â° C. for 22 hours of less than 65%, comprising:a) 100 parts by weight of a hydrogenated polymer comprising at least two vinyl-substituted aromatic hydrocarbon polymer blocks and at least one conjugated diene polymer block, b) 10 to 150 parts by weight of at least one of a homo- or co-polymeric polyphenylene ether resin comprising a binding unit represented by the general formula, wherein R1, R2, R3, and R4, independently are a hydrogen atom, a halogen atom and/or a hydrocarbon group, c) 10 to 500 parts by weight of a substantially amorphous polyolefin or hydrogenated polydiene, and d) 5 to 75 parts by weight of a diblock polymer comprising a first block comprising vinyl-substituted aromatic hydrocarbon monomer units and a second block comprising conjugated diene monomer units, and wherein said diblock polymer comprises between about 5 to 50 percent by weight vinyl-substituted aromatic hydrocarbon monomer units.
