Title:
PHENYL ANHYDRIDE-ETHYLENE OXIDE QUATERNARY COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2023/045898
Kind Code:
A1
Abstract:
The present invention relates to a phenyl anhydride-ethylene oxide quaternary copolymer. For the phenyl anhydride-ethylene oxide quaternary copolymer, preparation raw materials comprise copolymer monomers and a catalyst; the copolymer monomers are selected from ethylene oxide, propylene oxide, phenyl anhydride, and carbon dioxide. Under the control of the preparation raw materials and conditions of this system, it can be ensured that the prepared copolymer is of an irregular structure or a block structure, thereby ensuring that ethylene oxide exists in the middle of phenyl anhydride, then ensuring that a prepared material have a high internal plasticization effect, and ensuring that the molecular weight can reach 1.0×105 g/mol and the reaction time is shortened. The application prospect of the prepared material in the plastic field is increased while ensuring that the prepared material has good degradation performance.
