摘要

采用阳离子聚合法制备了聚angelicalacton -接枝聚苯乙烯共聚物。增加共聚物中苯乙烯单元的比例可以提高共聚物的强度性能并增加其脆性。增加共聚物中聚angelicalactone(PAL)的含量可以提高所制材料的弹性。所制得的共聚物主要由聚苯乙烯(PS)和聚苯乙烯(PAL)组成，其中苯乙烯键(4-烷氧基- 3-烯酸单元)的含量很少。苯乙烯共聚物中α-angelicalactone(AL)的低含量提高了共聚物的氧化稳定性。所得到的聚丙烯酸酯接枝聚合物具有符合通用聚丙烯酸酯要求的物理和机械性能

Synthesis and Properties of Polymers Based on Styrene and α-angelicalactone

Polyangelicalactone-graft-polystyrene copolymers were obtained through cationic polymerization. Increasing the portion of styrene units in the copolymers improves the strength properties and increases fragility. Increasing the polyangelicalactone(PAL) content in the copolymers increases the elasticity of the materials obtained. The obtained copolymers are greatly a composition of PAL and polystyrene (PS)with a small content of bonds of styrene-units of 4-alkoxypent‑3-enoic acid.Low α-angelicalactone(AL) content in styrene copolymers improves the oxidative stability of the copolymers. The resulting PAL‑graft-PScopolymers have physical and mechanical properties corresponding to the requirements for general-purpose PS
