VINYL POLYMER POWDER, CURABLE RESIN COMPOSITION, AND CURED PRODUCT

摘要

A vinyl polymer powder, a curable resin composition containing the vinyl polymer powder and a curable resin, and a cured product obtained by curing the curable resin composition are provided. The vinyl polymer powder contains a vinyl polymer of which the glass transition temperature is 120° C. or higher and the mass average molecular weight is 100,000 or more, has excellent dispersibility in the curable resin composition, and rapidly turns the curable resin composition into a gel state by heating at a predetermined temperature in a short time. Further, the vinyl polymer powder decreases the linear expansion coefficient of the obtained cured product, and improves the crack resistance.
