Abstract

Synthesis of polymers with hemiacetal ester moieties in the side chain by radical copolymerization of 1-alkoxyethyl methacrylate with various vinyl monomers and their thermal dissociation behavior are described. Radical copolymerization of 1-alkoxyethyl methacrylates with vinyl monomers was carried out in the presence of 2,2′-azoisobutyronitrile at 60 °C to afford the corresponding copolymers with hemiacetal ester moieties in the side chain. The thermal dissociation behavior of the obtained copolymers was examined by means of TG-DTA measurements to observe that the dissociation temperatures of hemiacetal ester units depended on their comonomer components. The polarity of the comonomers and the ability to form hydrogen-bonding were key forces to control their thermal dissociation behavior.
