VINYL POLYMER POWDER, CURABLE RESIN COMPOSITION, AND CURED PRODUCT

摘要

The present invention provides: a vinyl polymer powder that comprises a vinyl polymer having a glass transition temperature of at least 120°C and a mass average molecular weight of at least 100,000, has superior dispersibility in a curable resin composition, rapidly causes the curable resin composition to be in a gel state by means of heating for a short period of time at a predetermined temperature, and can cause the further obtained cured product to have a low coefficient of linear expansion and favorable cracking resistance; a curable resin composition containing the vinyl polymer powder and a curable resin; and a cured product obtained by curing the curable resin composition.
