New Thermosensitive microgel particles produced by using N-vinylcaprolactam(VCL) N-vinylpyrrolidone(NVP) and N,N’-methylenbisacrylamide(MBA).The microgel has been studied by Fourier transformation infrared spectroscopy(FT-IR),dynamic light scatteringand(DLS) and Atomic Force Microscopy(AFM).The influence of the comonomer on polymerization characteristics of such Thermosensitive particles was studied.A dramatic decrease in the liquid dynam volume diameter(Dz) is observed during the phase transition near 37°C.The surface of the microgel particles is sphericity when the weight of NVP is the weight of VCL 10 wt%.

A dramatic decrease in the liquid dynam volume diameter (Dz) is observed during the phase transition near 37 ° C.
