## Abstract Terpolymers based on __N__‐isopropylacrylamide, sodium 2‐acrylamido‐2‐methyl‐propanesulfonate, and __N__‐__tert__‐butylacrylamide were synthesized by free‐radical copolymerization with 2,2′‐azobisisobutyronitrile as an initiator. The lower critical solution temperatures (LCSTs) of the l

✦ Synopsis
The swelling and adsorption behavior of poly(N-isopropylacrylamide)-Si02 hybrid gels, derived from copolymerization of N-isopropylacrylamide and 3-methacryloxypropyltrimethoxysilane (MPTMOS) and following hydrolysis and condensation, were investigated.
The hybrid gels exhibited temperature dependence of both the swelling ratio and adsorption of solutes, and their temperature dependence was related to the MPTMOS content in the hybrid gels. In addition, the modification of thermosensitive properties of the hybrid gels could be achieved by treatment with other silane compounds.
