POLYMER PARTICLE, RESIN COMPOSITION CONTAINING SAME, AND MOLDED BODY

摘要

A polymer particle is obtained by polymerizing a monomer in the presence of a phosphate salt represented by the following formula (1). The polymer particle contains 0.01 to 1.0 part by mass of the phosphate salt to 100 parts by mass of the polymer particle. A resin composition and a molded article using such a polymer particle are excellent in thermal stability and resistance to moist heat, and the color tone of the resin has little change before and after the blending of the polymer particle.
In the formula (1), R 1 represents an alkyl group having 10 to 18 carbon atoms, R 2 represents an alkylene group having 2 to 3 carbon atoms, M represents an alkaline metal or an alkaline earth metal, m represents an integer of 1 to 20, and n represents 1 or 2.
