Ethyl 1-[(4-hydroxyphenyl)aminocarbonyl)]-2-vinylcyclopropane carboxylate has been oligomerized using horseradisch peroxidase as catalyst. The oligomerization was achieved in the presence of cyclodextrine at room temperature in phosphate buffer (pH 7). The oligomer formed was cross-linked via free radical polymerization.
Summary: Novel water‐soluble hydrophobically associative polymers, comprising sodium 2‐acrylamido‐2‐methylpropansulfonate , N,N‐dimethylacrylamide and different amounts of a hydrophobically associative macromonomer, were synthesized in an aqueous medium. Formation of a rotaxane‐like complex of this macromonomer, with randomly methylated β‐cyclodextrin, was studied. In addition, a side chain of polyrotaxane, comprising this complex and methyl methacrylate, was synthesized via ATRP. These polymers were characterized by dynamic light scattering and fluorescent‐probe technique. Effects of methylated β‐cyclodextrin on micelle formation of the polymers were also studied.The side‐chain polyrotaxane.magnified imageThe side‐chain polyrotaxane.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
