Abstract:
1. A weatherstrip composition comprising the following polymer A group and polymer B group, Polymer A group: A polymer group made up of a domain Polymer B group: A polymer group made up of at least one thermoplastic resin selected from propylene polymer, ethylene/propylene copolymer, and ethylene/propylene/α-olefin terpolymer (where the α-olefin has from 3 to 20 carbons), wherein the storage elastic modulus E′ measured under the same conditions is from 5 to 17 GPa, and the loss tangent tan δ is greater than 0.4 and no more than 0.7 (the amount in which polymer B group is contained is from 0 to 40 wt % based on the total weight of the weatherstrip composition), wherein domain
