POLYCARBONATE COMPOSITION EXCELLENT IN SLIP PROPERTIES AND WEATHERABILITY

摘要

PROBLEM TO BE SOLVED: To obtain the subject composition capable of recycling and being used as a surface material of a polycarbonate lamination body by bringing the polycarbonate resin to contain cross-linked polystyrene beads and a specific UV absorber. SOLUTION: This carbonate composition contains (B) 0.01-2.0 wt.% of cross- linked polystyrene beads and (C) 1-20 wt.% of the sum total of UV absorbers expressed by formulas (i) and (ii) in a used ratio of [the ingredient (i)] : [the ingredient (ii)] =(95:5)-(5:95) in (A) a polycarbonate resin. The ingredient B preferably has a spherical shape, a uniform particle size and 1-100μm average particle size. Laminates having excellent slip properties and weatherability and capable of being recycled are obtained by laminating the composition as a surface layer material without spoiling characteristics of the polycarbonate resin.
