Title:
DEGRADABLE COMPOSITE POLYMER HAVING HIGH DUCTILITY, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/104073
Kind Code:
A1
Abstract:
The present invention provides a degradable composite polymer having high ductility, and a preparation method therefor. The degradable composite polymer is prepared from the following raw materials in parts by weight: 1-99 parts of PHBV, 1-99 parts of PPCP, 0.1-20 parts of a compatibilizer, and 0.1-15 parts of a functional additive. According to the degradable composite polymer of the present invention, by adjusting the addition ratio of PPCP to PHBV and combining a specific compatibilizer and a plurality of specific functional additives, production costs are reduced, the degree of crystallization of a composite copolymer is reduced, mechanical properties of the degradable composite polymer are improved, the compatibility of the polymer and the thermal stability and anti-photoaging ability of the polymer are improved, applications of the composite copolymer in thin films, sheets, injection molded products, and foamed products are increased, and the degradable composite polymer of the present invention is suitable for large-scale industrial production.
