ADHESIVE FOR SHAPED ARTICLE PRODUCTION, ADHESIVE COMPOSITION AND SHAPED ARTICLE USING THOSE

摘要

Disclosed is an adhesive for shaped article production, which contains one or more of active hydrogen compounds (a) selected from (a1)-(a3) below and having an active hydrogen-containing group and a vinyl polymerizable functional group represented by the general formula (1) below. This adhesive may contain the active hydrogen compound (a) and an active hydrogen compound (b) which has no vinyl polymerizable functional group. (a1) A partial ester of a polyol with an unsaturated carboxylic acid or a partially unsaturated alkyl ether of a polyol (a2) A partially amidated product of an amine with an unsaturated carboxylic acid or a partially unsaturated alkylated product of an amine (a3) A partial thioester of a polythiol with an unsaturated carboxylic acid or a partially unsaturated alkylthioether of a polythiol (1) (In the formula, R represents a hydrogen, an alkyl group having 1-15 carbon atoms or an aryl group having 6-21 carbon atoms.) By using such an adhesive, there can be obtained excellent shaped articles such as wooden boards having excellent mechanical strength, shaped articles using paper or pulp as a raw material, heat pressed foams and urethane chip sponge shaped articles improved in hardness, even when the amount of the adhesive used therefor is reduced.
