Title:
VIBRATION-INSULATING RUBBER COMPOSITION
Document Type and Number:
Japanese Patent JPH08134269
Kind Code:
A
Abstract:
PURPOSE: To obtain a vibration-insulating rubber compsn. which has a high tan δ value and a low dynamic-to-static modulus ratio by using a coplymer of isobutylene with a partially brominated p-methylstyrene.
CONSTITUTION: Isobutylene is coplymerized with a partially brominated p- methylstyrene to give a coplymer having a bromine content of 0.8-2wt.%. The copolymer is blended with a diene rubber in a wt. ratio of (10:90)-(100:0).
