Title:
HIGH-TOUGHNESS COMPOSITION OF SEMI-AROMATIC CARBON DIOXIDE-BASED COPOLYMER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/045850
Kind Code:
A1
Abstract:
The present invention provides a high-toughness composition of a semi-aromatic carbon dioxide-based copolymer and a preparation method therefor. The composition is prepared from the semi-aromatic carbon dioxide-based copolymer, PBAT, a filler and a compatibilizer as raw materials. By means of methods such as regulating and controlling the structure of a molecular chain segment in the semi-aromatic carbon dioxide-based copolymer, the glass transition temperature of the composition is increased, and the biodegradability of the composition is improved, and a biodegradable material with good transparency, high light transmission, and a mechanical property, processability and usage performance that meet practical application is obtained.
