(METH)ACRYLIC RESIN COMPOSITION AND ITS USE

PROBLEM TO BE SOLVED: To provide a (meth)acrylic resin composition which can prevent the cracking of a molding when the resin is heated for molding, and obtain a molding which is excellent in low shrinkage, transparency, and surface gloss. SOLUTION: This (meth)acrylic resin composition comprises a (...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a (meth)acrylic resin composition which can prevent the cracking of a molding when the resin is heated for molding, and obtain a molding which is excellent in low shrinkage, transparency, and surface gloss. SOLUTION: This (meth)acrylic resin composition comprises a (meth)acrylic ester monomer, a (meth)acrylic ester polymer, and a peroxy bond contg. polymer formed with a vinyl monomer and a peroxy bond donor. The peroxy bond contg. polymer has a definite crosslinking structure. An artificial marble is obtd. by compounding an inorg. filler and a polymerization initiator to the (meth)acrylic resin composition.
