The present invention provides a reinforced polyester resin composition having a high crystallization rate and superior moldability, from which a molded article having low shrinkage anisotropy and superior surface properties can be obtained.
The reinforced polyester resin composition according to the present invention comprises, with respect to 100 parts by mass of a polyester resin,
0.01 to 400 parts by mass of an inorganic filler as component (A) and
0.001 to 10 parts by mass of a metal salt of a sulfonamide compound as component (B), the metal salt of the sulfonamide compound having a structure represented by the following Formula (1):
(wherein, R1 and R2 independently represent a hydrogen atom or the like; R1 and R2 are also optionally linked together to form a cyclic group; n represents number of 1 or 2; when n is 1, M represents an alkali metal atom or the like; when n is 2, the plural R1s and R2s are each optionally different; M represents a divalent metal atom or linking group; and when M is the linking group, either of R1 and R2 is an alkali metal).
本发明提供了一种具有高结晶率和优异成型性的增强聚酯树脂组合物,通过该组合物可以获得具有低收缩各向异性和优异表面特性的成型制品。
根据本发明的增强聚酯树脂组合物,相对于 100 质量份的聚酯树脂,包括
0.01 至 400 质量份的无机填料(A)和
0.001 至 10 重量份的磺酰胺化合物金属盐作为组分(B),磺酰胺化合物金属盐的结构如 下式(1)所示:
(其中,R1 和 R2 独立地代表氢原子或类似物;R1 和 R2 还可选择连接在一起以形成环状基团;n 代表 1 或 2 的数目;当 n 为 1 时,M 代表碱金属原子或类似物;当 n 为 2 时,复数的 R1s 和 R2s 可选择各不相同;M 代表二价金属原子或连接基团;当 M 为连接基团时,R1 和 R2 中的任一者为碱金属)。
