THERMOSETTING RESIN COMPOSITION

摘要

A thermosetting resin composition is provided to realize improved crosslinking density, mechanical properties and heat resistance, and to cause no yellowing even at high temperature. A thermosetting resin composition comprises a copolymer(A) of (a1) an unsaturated carboxylic acid or anhydride thereof; (a2) an epoxy group-containing unsaturated compound; (a3) a trialkoxysilane-based unsaturated compound; and (a4) an olefinic unsaturated compound. The copolymer(A) comprises repeating units derived from the trialkoxysilane-based unsaturated compound in an amount of 5-60 wt%.
