Production manner null of radical hardening possible

摘要

PURPOSE:To obtain the title resin readily radical-curable, capable of giving high-toughness cured resins of good balance between elongation and mechanical strength, and also useful as an adhesive, by reaction between an isocyanate- terminated polyester and a specific vinyl ester resin. CONSTITUTION:The objective resin can be obtained by reaction between (A) a polyester =5,000 in number-average molecular weight with its terminal group being virtually isocyanate group and (B) a vinyl ester resin having in one molecule at least two (meth)acryloyl groups and hydroxyl groups.
