Title:

BIO-DEGRADABLE POLYESTER COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2018/014561

Kind Code:

A1

Abstract:

Disclosed is a bio-degradable polyester composition, wherein, on the basis of the total weight of the biodegradable polyester composition, the content by weight of glycidyl methacrylate is 0.05 ppm -10 ppm. According to the present invention, by means of adding a trace of glycidyl methacrylate in a formula of the bio-degradable polyester composition, the content by weight of glycidyl methacrylate which ultimately remains in the biodegradable polyester composition is controlled to be 0.05 ppm -10 ppm, thus the compatibility of aliphatic-aromatic polyester and polylactic acid base materials in the biodegradable polyester composition may be greatly improved so that the biodegradable polyester composition has excellent membrane material surface performance, and phenomena such as crystal points appearing on a membrane material due to the fluctuation of processing technology may be avoided.
