Abstract
Poly(N-isopropylacrylamide) (PNIPAAm) containing polydimethylsiloxane (PDMS) was synthesized using PDMS as crosslinking agent, and characterized by IR and DSC. It seems that the copolymer has separated phases, PNIPAAm and PDMS. The $T_g$ of PNIPAAm was decreased in accordance with the increase of PDMS-contents. The swelling behavior of polymer in water was examined with the function of temperature and PDMS-contents as well. The equilibrium swelling ratio of polymer in water was decreased with increasing PDMS-contents, but lower critical solution temperature (LCST) was not significantly affected by the incorporated PDMS-contents.?????x??????D???��?????????��?����????????????????Y?��?��?��??????????��??????��??????????????????��??????????????����?��????????????����?��??????????
