Carbon count of the damping Characteristic adhesion agent composition and the damping Characteristic pressure sensitive adhesive sheet null

摘要

PROBLEM TO BE SOLVED: To obtain a vibration-damping adhesive composition having excellent adhesion and vibration-damping properties at a high temperature range of (40-80°C).;SOLUTION: The vibration-damping adhesive composition comprises (A) an acrylic polymer of 100 pts.wt. comprising, as a principal monomer unit, an alkyl (meth)acrylate in which the alkyl group has any one of 4-12C and (B) a compound of 5-50 pts.wt. having at least two in total of a hydroxyphenyl group and/or a substituted hydroxyphenyl group in the molecule.;COPYRIGHT: (C)2003,JPO
