Thermo- and pH-sensitive amphiphilic gels of copolymers of vinyl ether of ethylene glycol

Novel thermo‐sensitive linear and crosslinked copolymers of vinyl ether of ethylene‐glycol and vinyl butyl ether have been synthesized by gamma‐irradiation copolymerization. The effect of comonomer hydrophobicity, neutral salts addition and nature of cations and anions on the position of lower criti...

Description
Summary:	Novel thermo‐sensitive linear and crosslinked copolymers of vinyl ether of ethylene‐glycol and vinyl butyl ether have been synthesized by gamma‐irradiation copolymerization. The effect of comonomer hydrophobicity, neutral salts addition and nature of cations and anions on the position of lower critical soluble temperature of water‐soluble copolymers and swelling‐deswelling behavior of networks is demonstrated. The combination of thermosensitivity and pH sensitivity of hydrogels are realized in the case of crosslinked terpolymers. Copyright © 1999 John Wiley & Sons, Ltd.
