Abstract

Diblock copolymers of vinyl ethers with two thermosensitive segments possessing different phase separation temperatures (T PS) have been synthesized by sequential living cationic copolymerization. Examples include 2-(2-ethoxy) ethoxyethyl vinyl ether (EOEOVE) and 2- methoxyethyl vinyl ether (MOVE), which were sequentially polymerized using a cationogen/Et1. 5AlCl1. 5 initiating system in the presence of tetrahydrofuran to give ...
