Polyhedral oligomeric silsesquioxane(POSS) has been widely regarded as one of the most promising hybrid materials. The precursor has extensive thermal stability and stable oxidation sate. Click chemistry describes a class of chemical reactions that are easy to perform, give rise to their intended products in very high yields with little or no by products, work well under many conditions. Poly(N-isopropylacrylamide) was prepared via reversible addition-fragmentation chain transfer (RAFT) polymerization using the 1-cyano-1-methyl dithiobenzoate. New hybrid poly(N-isopropylacrylamide) containing poss was synthesized by a simple and versatile approach which is click coupling between azide functionalized POSS and alkyne-functionalized poly(N-isopro pylacrylamide).we also discuss their unique characteristics and properties demonstra ted by NMR, TGA, DSC, SEM, and FT-IR. |
