摘要

A series of H-shaped (PS)2PEG(PS)2 block copolymers with different PS chain lengths were prepared. The influence of different confinements active on the crystallization and self-nucleation (SN) behavior of the PEG blocks was investigated by differential scanning calorimetry (DSC). When the content of the crystalline block was high

a classical SN behavior was obtained. The block copolymer with PEG content of 49% (by weight) showed a classical SN behavior with a narrow self-nucleation domain and had bimodal crystallization exotherms. When the PEG dispersed as separated microdomains in the block copolymer

the self-nucleation domain disappeared and only annealing was observed.

Abstract

the self-nucleation domain disappeared and only annealing was observed.
