Abstract: The ABA block copolymers of polyethylene glycol(PEG) as B block and poly N-isopropylacrylamide(PNIPA) as A block were synthesized by means of radical polymerization with one step. The block polymers exhibit thermosensitive behavior at a higher LCST temperature than homopolymer of NIPA.

Key words: Block copolymer, Radical polymerization, Thermosensitive behavior
