REACTIVE CROSSLINKED RESIN FINE PARTICLE, METHOD FOR PRODUCING THE SAME AND THERMOSETTING COMPOSITION CONTAINING THE FINE PARTICLE

摘要

PROBLEM TO BE SOLVED: To obtain a reactive crosslinked resin fine particle that improves mechanical strength of a cured material by thermal curing and a thermosetting composition containing the reactive crosslinked resin fine particle. SOLUTION: The reactive crosslinked resin fine particle is obtained by subjecting a crosslinked resin fine particle (A) and a compound (D) containing an unsaturated double bond in a main chain to a graft reaction. The crosslinked resin fine particle (A) is a fine particle obtained by radically polymerizing a reactive functional group-containing functional ethylenic unsaturated monomer (a) with a monofunctional ethylenic unsaturated monomer (b) except the monomer (a) and a polyfunctional ethylenic unsaturated monomer (c) and the compound (D) containing the unsaturated double bond in the main chain is a compound containing a double bond and a functional group to be reacted with the reactive functional group in the main chain.
