ACRYLIC POLYMER MICROPARTICLE, ITS PRODUCTION METHOD, PLASTISOL, AND MOLDING

摘要

PROBLEM TO BE SOLVED: To provide acrylic polymer microparticles which exhibit excellent moldability in a molding process where a molding material needs to be lowly viscous and can give a molding excellent in mechanical properties such as tensile strength and tearing strength, to provide a production method for the microparticles, to provide an acrylic plastisol composition using the microparticles, and to provide a molding of the composition. SOLUTION: What is provided is: acrylic polymer microparticles having a ratio (DvP/DvP) of 1.3 to 3.5 (wherein DvPis the volume-mean primary particle diameter, and DnPis the number-mean primary diameter); a production method for producing the microparticles; a plastisol composition comprising the microparticles and a plasticizer; and a molding prepared by molding the plastisol composition.
