ABSTRACT:
A weatherstrip composition includes the following polymer A group and polymer B group, Polymer A group. A polymer group is made up of a domain1consisting of crosslinked product of a polymer selected from a group consisting of ethylene polymer, ethylene/α-olefin copolymer (where the α-olefin has from 3 to 20 carbons), ethylene/α-olefin/diene copolymer (where the .alpha.-olefin has from 3 to 20 carbons), homopolymer rubber of a conjugated diene monomer, copolymer polymerized with a conjugated diene monomer and an aromatic vinyl monomer, and hydrogenated copolymer polymerized with a conjugated diene monomer and an aromatic vinyl monomer (where the hydrogenation of all double bonds except for the aromatic groups is at least 50%), and a domain2is made up of crosslinked product of ethylene polymer or ethylene/α-olefin copolymer (where the α-olefin has from 3 to 20 carbons).
