摘要

Poly(ethylene succinate)-

-poly(butylene carbonate) (PES-

-PBC) multiblock copolymers were synthesized

via

chain extension. When prepolymer molecular weight is below 2000 g/mol

PES and PBC become fully miscible

enhancing compatibility. Incorporating PBC tunes crystallinity

mechanical properties

and degradation

yielding tough

biodegradable materials with promising applications.

Abstract

In this study

a series of poly(ethylene succinate)-

-poly(butylene carbonate) (PES-

-PBC) multiblock copolymers were prepared through the chain-extension reaction of hydroxyl-terminated PES (PES-OH) and hydroxyl-terminated PBC (PBC-OH) prepolymers with 1

6-hexmethylene diisocyanate (HDI) as a chain extender. The effects of the prepolymer molecular weight and content on the structure and application properties of the PES-

-PBC copolymers were systematically investigated using various techniques. It was found th

at the compatibility of PES and PBC blocks in PES-

-PBC copolymers can be greatly enhanced by lowering the length of the prepolymers

and the amorphous phase of the PES and PBC chain segments in the PES-

-PBC copolymer would transform from immiscibility and partial miscibility to miscibility when the number-average molecular weight (

) of the PES-OH and PBC-OH prepolymers is less than 2000 g/mol. Only the crystal structure of bare PES can be observed in the wide-angle X-ray diffraction (WAXD) spectrum of the PES-

-PBC copolymers

but their crystallinity degrees were found to decrease with increasing PBC fraction. The thermal behavior

crystallization performance

rheological properties

mechanical properties

and degradation properties of the PES-

-PBC multiblock copolymers can be easily modulated by altering the block length and composition of the prepolymers

offering potential applications in biodegradable materials.
