Title:
POLYMER MICROPARTICLE-DISPERSED RESIN COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2012/093631
Kind Code:
A1
Abstract:
Provided is a novel means for modifying a resin with which an excellent and balanced elastic modulus (rigidity), heat resistance, toughness, and impact resistance are obtained. A polymer microparticle-dispersed resin composition comprising 100 parts by weight of resin and 0.1 to 150 parts by weight of polymer microparticles having at least two layers of a crosslinked polymer layer and a coating polymer layer, wherein the particle dispersion rate of the polymer microparticles in the resin is 50% or greater and the crosslinked polymer layer is formed from 50 to 99 wt% of one or more monomers the homopolymer Tg of which is 0ºC or greater and 50 to 1 wt% of one or more monomers the homopolymer Tg of which is less than 0ºC.
