(METH)ACRYLIC POLYMER PARTICLES, PROCESS FOR PRODUCTION THEREOF, PLASTISOL COMPOSITIONS MADE BY USING THE PARTICLES, AND ARTICLES MADE BY USING THE COMPOSITIONS |
摘要 |
<p>The invention provides industrially useful (meth)acrylic polymer particles capable of forming a plastisol which is so excellent in storage stability, particularly at 40°C or above, that it little causes gelation in storage and can be kept in a sol state and which can give moldings excellent in flexibility and chipping resistance; a process for the production of the particles; and plastisol compositions made by using the particles. A process for the production of (meth)acrylic polymer particles which comprises polymerizing a monomer or monomer mixture (B) in the presence of a polymer (a) obtained by the polymerization of a monomer or monomer mixture (A) to form a polymer (b), wherein the glass transition temperature (Tg) of the polymer (a) is 90°C or above as calculated from the FOX equation and the solubility parameters of the polymers (a) and (b) are 19.90(J/cm<SUP>3</SUP>)<SUP>1/2</SUP> or below and 20.22(J/cm<SUP>3</SUP>)<SUP>1/2</SUP> or above respectively.</p> |
