Title:
POLYESTER SEGMENTED COPOLYMER AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/062428
Kind Code:
A1
Abstract:
The present invention discloses a polyester segmented copolymer, characterized by the structure shown in the formula (I). The present invention further discloses a method for preparing the polyester segmented copolymer. The present invention polymerizes a silicon-containing unit into a polyester molecular chain by copolymerization, and the resultant copolymer has excellent low-temperature resistance and lower surface tension, addressing the issue of non-resistance of polyester resins to low temperatures, and expanding applications of polyester resins in the fields of fibers, thin films, blow molding, and engineering plastics.
