Methacryloyl‐L‐valine methyl ester (MAVM) and maleic anhydride (MAn) were photopolymerized without initiator in dioxane at 35°C. Copolymer having a 1:1 molar ratio of the monomers was obtained regardless of both molar ratio of monomers in the feed and polymerization time. The circular dichroism (CD) spectrum of the copolymer before and after hydrolysis showed the induction of asymmetric centers into the polymer main chain. Spectroscopic and kinetic studies suggested the alternating and stereoregular copolymerization of MAVM and MAn, in which a charge transfer complex with a 1:1 molar ratio of monomers participated.

“…The fi rst example of asymmetric polymerization of optically active chiral vinyl monomers was the copolymerization of ( S ) -α -methylbenzyl methacrylate with maleic anhydride in the presence of AIBN to give the polymer, which showed an optical rotation of [ α ] D +23 ° after the removal of chiral ( S ) -α -methylbenzyl group [129] . Another example is the copolymerization of optically active styrene derivative ( 82 ) with N -phenylmaleimide ( 5 , R = Ph).…”

“…The first successful asymmetric synthesis of a polymer was accomplished by Beredjick and S c h u e r~h .~~? 43 1-a-Methylbenzyl methacrylate was copolymerized with maleic anhydride using free radical initiation. After removal of the asymmetric centers by reduction, the copolymer exhibited a rotation opposite in sign to that of its precursor.…”
