Abstract:Optically active (+)-2-endo-acetoxy-5-endo-bornyl methacrylate (ABMA) was prepared from (+)-camphor. The free-radical homopolymerization of ABMA and its copolymerization with achiral methyl methacrylate (MMA) or styrene (St) were carried out with 2,2'-azoisobutyronitrile in benzene. Effects of temperature and reaction time on the copolymerization were discussed. The monomer reactivity ratios (r,, r2) for poly(ABMA-co-MMA) and poly(ABMA-co-St) as well as Q and e values for the chiral ABMA in the copolymerizatio… Show more
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.
