ACRYLIC SYRUP COMPOSITION FOR HIGHLY VISCOELASTIC RESIN, HIGHLY VISCOELASTIC MOLDED ARTICLE USING SAID SYRUP, USE THEREOF, AND METHOD FOR MANUFACTURING HIGHLY VISCOELASTIC ACRYLIC SHEET

摘要

PROBLEM TO BE SOLVED: To provide an acrylic syrup composition for molding a highly viscoelastic resin of an acrylic polymer that can substitute a highly viscoelastic silicone polymer conventionally used for a cushioning material, a shock- absorbing material, a cushioning and vibration-proof material, etc., and is less expensive than the highly viscoelastic silicone polymer, to provide a manufacturing method therefor and to provide use of the syrup.;SOLUTION: In an acrylic syrup composition for a highly viscoelastic resin containing an initial-stage uncrosslinked polymer from an acrylic monomer, a vinyl monomer having (B) a crosslinkable functional group at the end of a side chain is made to act on the initial-stage polymer having, as an uncrosslinked point, at least one functional group (A) selected from a hydroxy group, a carboxyl group, a glycidyl group, an isocyanate group, an alkoxysilyl group, an amino group and an amide group, so that the uncrosslinked point is substituted by the vinyl group.;COPYRIGHT: (C)2003,JPO
