Synthesis and properties of a stimulus-responsive block polymer.

ABSTRACT: In this study, the synthesis of small molecules and use of an improved "one-pot" method to synthesize the reversible addition-fragmentation chain transfer polymerization (RAFT) reagents have been reported. By comparing with the RAFT reagents synthesized by the traditional "step-by-step" method, it was observed that the reagents synthesized by the two methods had the same structure, however, the improved "one-pot" preparation method results in a significantly higher yield. Subsequently, two different macromolecular CTA segments (PVP-CTA-PVP and PDMAEMA-CTA-PDMAEMA) were prepared by RAFT polymerization, followed by the synthesis of the block polymer PDMAEMA-b-PVP-CTA-PVP-b-PDMAEMA. Through FITR, NMR, GPC and DLS analysis of the block polymer, it was observed that the isotactici
