Triethyleneglycol monomethacrylate(TREGMA) was synthesized by two steps and characterized using IR and 1H-NMR.It then was copolymerized with N-isopropylaeryl-amide (NIPAM) using N
N-methylene bisacrytamide (BA) as crosslinker through surfaetant-free emulsion polymerization to prepare temperature-sensitive microgels containing functional hydroxy groups.Investigation on the deswelling behavior of the microgels indicated that the microgels prepared had good temperature sensitivity
and the incorporation of TREGMA made the volume-phase transition temperature of the microgels shifted to higher temperature This type of mierogels might be good candidate for biomedical materials.
