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

Abstract

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
