Abstract

Linear and crosslinked copolymers of a vinyl ether of ethylene glycol (2‐hydroxyethyl vinyl ether, (1)) and butyl vinyl ether (2) are synthesized by α‐irradiation polymerization. It is shown that the linear copolymers exhibit a phase separation phenomenon in dependence of the temperature due to the destruction of hydrogen bonds and the enhancement of hydrophobic interaction in aqueous solution. The processes of reversible swelling or shrinking upon temperature change are demonstrated for polymer networks.
