摘要

Dynamic Monte Carlo simulations were used to investigate stereocomplex crystallization in cyclic polymer systems. The cyclic polymer blend exhibits weakest stereocomplexation ability

while the cyclic block copolymers have stronger stereocomplexation ability than the linear diblock copolymer due to the synergy between the ring chain topology and the block copolymer structure.

Abstract

Stereocomplex crystallization in cyclic polymer blend and cyclic block copolymers was investigated by means of dynamic Monte Carlo simulations. Five polymer systems (linear polymer blend

linear diblock copolymer

cyclic polymer blend

cyclic diblock copolymer and tetrablock copolymer) were established. It was interestingly found that the cyclic polymer blend exhibited the weakest stereocomplexation ability

while the two cyclic block copolymers showed stronger stereocomplexation ability than the linear diblock copolymer. This abnormal improved stereocomplexation ability of the cyclic block copolymers can be attributed to the synergy between the ring chain topology and the block copolymer structure. Compared with the linear block copolymers

the ring chain topology confined segmental motions of cyclic polymer chains to smaller regions

and then the segments belonging to the different blocks in the cyclic block copolymers have more chance to contact with each other. In this way

the cyclic block copolymers had better miscibility between segments belonging to different types of blocks

leading to the stronger stereocomplexation ability.
