Abstract

PURPOSE: To improve transparency of polyether ester block copolymer while preserving its improved properties, by reacting a specific polyether ester block copolymer with polycarbonate.
CONSTITUTION: (A) A polyether ester block copolymer comprising (i) an ester unit consisting of a carboxylic acid ingredient of an aromatic dicarboxylic acid as a main ingredient and a glycol ingredient of 2W10C glycol as a main ingredient and (ii) an ether ester unit consisting of an acid ingredient of an aromatic dicarboxylic acid as a main ingredient and a poly(oxyalkylene) glycol ingredient having an average molecular weight 350W6,000 and an atom number ratio of carbon to oxygen of 2.0W10.5:1, and 5W85wt%, based on total weight ingredient ii is reacted with (B) polycarbonate in a weight ratio of A/B of 95/5W30/70 under reduced pressure preferably at 220W250°C.
