VIBRATION-DAMPING COMPOSITION AND PROCESS FOR PRODUCING VIBRATION-DAMPING COMPOSITION

摘要

A vibration-damping composition comprising: a base which is a mixture of an ethylene/methacrylic acid copolymer with a rosin resin; and an active ingredient contained in the base so as to increase the dipole moment of the base. The proportion by weight of the ethylene/methacrylic acid copolymer to the rosin resin (EM: rosin) is from 70:30 to 30:70.
