Title:
POLYBASIC-ACID-CONTAINING POLYHYDROXYALKANOATE COMPOSITION AND POLYHYDROXYALKANOATE MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2024/087609
Kind Code:
A1
Abstract:
The present invention relates to the technical field of polymer materials, and particularly relates to a polybasic-acid-containing polyhydroxyalkanoate composition and a polyhydroxyalkanoate molded body. The polyhydroxyalkanoate composition comprises a polyhydroxyalkanoate and a polybasic acid compound. The polybasic acid compound can reduce the effect of thermal degradation of polyhydroxyalkanoates during thermoplastic processing preparation of various molded bodies on properties of molded bodies to a certain extent, so as to maintain the molecular weight of the molded bodies, and reduce the melt flow rate. Using the composition of the prevent invention in preparing various molded bodies can effectively avoid potential safety hazards caused by high-activity substances such as organic peroxides, such that the difficulty of reaction quantitative control is reduced, and the processing operation is thus safer and more convenient, thereby effectively improving the processing efficiency of polyhydroxyalkanoate resin, and enabling prepared molded bodies to have higher toughness and better quality.
