Title:
熱安定性が改良されたポリカーボネート組成物
Document Type and Number:
Japanese Patent JP5566837
Kind Code:
B2
Abstract:
Composition comprises a melt polycarbonate, at least one phosphine compound (I) and n-octadecyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate. Composition comprises a melt polycarbonate, at least one phosphine compound of formula (Ar1-P(R1a)(Ar2)) (I) and n-octadecyl-3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate. Ar1, Ar2 : optionally substituted aryl; R1a : optionally substituted aryl, -(CH 2) n-P(R) 2(a1), -(CH 2) n-P(R)-(CH 2) m-P(R) 2(a2), -CH=CH-P(R) 2(a3), -C?=C-P(R) 2(a4), -Ar3-P(R) 2(a5), dioxolane group of formula (a6), binaphthalenyl group of formula (a7) or -(CH 2) m-C(((CH 2) m-P(R) 2) 2)-(CH 2) m-H (a8), where the hydrogen atoms of (a1)-(a3) are optionally replaced by substituents; Ar3 : 6-14C-aryl; R : optionally substituted 6-14C-aryl; and n, m : 1-7. Where R1a optionally further contains 4-phenyl-phenyl- or alpha -naphthyl, when both Ar1 and Ar2 are 4-phenylphenyl or alpha -naphthyl (both contains further substituents). An independent claim is included for producing the composition, comprising producing polycarbonate by melt transesterification reaction of bisphenols and carboxylic acid diesters. [Image].
