POLYMER PARTICLE, RESIN COMPOSITION CONTAINING SAME, AND MOLDED BODY

Title:

POLYMER PARTICLE, RESIN COMPOSITION CONTAINING SAME, AND MOLDED BODY

Document Type and Number:

WIPO Patent Application WO/2006/093271

Kind Code:

A1

Abstract:

Disclosed is a polymer particle obtained by polymerizing a monomer in the presence of a phosphate salt represented by the formula (1) below. The polymer particle is characterized by containing 0.01-1.0 part by mass of the phosphate salt per 100 parts by mass of the polymer particle. When such a polymer particle is blended in a resin, change in the color tone of the resin is suppressed without decreasing thermal stability or wet heat resistance of a molded body. A resin composition and molded body using such a polymer particle are excellent in thermal stability and wet heat resistance, and the color tone of the resin does not change very much before and after the blending of the polymer particle. (1) (In the formula, R¹ represents an alkyl group having 10-18 carbon atoms; R² represents an alkylene group having 2 or 3 carbon atoms; M represents an alkali metal or an alkaline earth metal; m represents a number of 1-20; and n represents 1 or 2.)
