Title:
RESIN COMPOSITION
Document Type and Number:
Japanese Patent JPS5920352
Kind Code:
A
Abstract:

PURPOSE: To provide a resin compsn. having improved moldability as well as improved transparency, consisting of a polyarylate and a specified ester oligomer.

CONSTITUTION: A resin compsn. consists of a polyarylate (e.g. one obtd. from a mixture of terephthalic acid and isophthalic acid or their functional derivatives and bisphenol A or its functional derivative) and an ester oligomer obtd. by reacting a dihydric phenol or its functional derivative with a carbonate precursor, such as one obtd. reacting P-t-butylphenol-blocked bisphenol A with carbonic acid. While retaining excellent properties such as heat resistance, etc. inherent to the polyarylate, the moldability and transparency are improved and hence, the compsn, is useful as a molding material.
