Title:
変性スチレン-フマル酸共重合体、不飽和ポリエステル樹脂組成物、不飽和ポリエステル樹脂成型品及び廃プラスチックの利用方法
Document Type and Number:
Japanese Patent JP5022578
Kind Code:
B2
Abstract:
To provide a modified styrene-fumarate resin and a utilization method of a waste plastic aiming at effective utilization of resources by reusing the waste plastic as a low shrinkage material, and to provide an unsaturated polyester resin composition preserving low shrinking percentage and an unsaturated polyester resin molding with enhanced dimensional accuracy by using a styrene-fumarate resin.
This modified styrene-fumarate resin is obtained by dehydration reaction of the styrene-fumarate resin, obtained by hydrolyzing an unsaturated polyester resin with subcritical water, with alcohols or phenols.
