## Abstract Amino semitelechelic poly(__N__‐isopropylacrylamide) (PNIPAAm) was prepared by radical polymerization with aminoethanethiol hydrochloride as a chain‐transfer agent. Semi‐interpenetrating polymer network (semi‐IPN) hydrogels, composed of alginate and amine‐terminated PNIPAAm, were prepar

## a b s t r a c t We previously reported that a copolymer consisting of N-isopropylacrylamide (NIPAM) and benzophenone (BP) units, behaves as a photosensitizer showing temperature-controlled oxygenation activity in water (J. Am. Chem. Soc. 2006, 128, 8751). This polymer shows a heat-induced oxyge
A temperature-responsive cross-linked polymer gel was covalently grafted onto glass coverslips by electron beam irradiation. The grafted thickness and amount of polymer as well as the surface wettability increased with the initial monomer concentration. When the monomer concentration was 5 wt.%, the
## Abstract **Summary:** A series of semi‐interpenetrating, polymer network (semi‐IPN), hydrogel beads, composed of calcium alginate (Ca‐alginate) and poly(__N__‐isopropylacrylamide) (PNIPAAM), were prepared for a pH/temperature‐sensitive drug delivery study. The equilibrium swelling showed the ind
