摘要

Abstract

Copolymerization is a commonly employed method for optimizing the properties of polymer materials. Incorporating ether segments into polyesters main chain to obtain polyether-polyester copolymers is an effective strategy to realize the integration of multiple properties of polyester and polyether

and to develop more high-performance

multi-purpose polymer materials. Herein

the synthesis of poly(ether-ester)s is accessible by employing the biphenyl-linked heterodinuclear salen Cr-Al complex in the presence of PPNCl for the copolymerization of epoxides and

-caprolactone (CL). Monitoring the copolymerization process reveals that catalyst

exhibited good performance for the copolymerization of epoxides and CL

affording copolymers with a gradient sequence structure. The dynamic thermomechanical analysis (DMA) study indicates the obtained poly(ether-ester)s possess enhanced flexibility compared with the block copolymers or blend of PPO and PCL homopolymers with the same ratio. This study provides a theoretical basis for the preparation of high-performance polymer materials.

The content of ether linkage (EC) and the crossover ratio (CR) in the mixture can be calculated as follows: Ether content (EC) = {[A( δ = 3.30~3.71 ppm)-2A( δ = 5.0 ppm)]/3}/[A( δ = 4.0 ppm)/2+A( δ = 5.0 ppm)+[A( δ = 3.30~3.71 ppm)-2A( δ = 5.0 ppm)]/3] ; Crossover ratio (CR) = A( δ = 5.0 ppm)/[A( δ = 4.0 ppm)/2], where A is the integral area, respectively based on 1 H NMR analysis.
