A new chiral monomer, (+)-2-endo-acetyloxy-5-endo-bornyl methacrylate (ABMA), was synthesized. Homopolymerization of the ABMA and copolymerization of the chiral monomer with various achiral comonomers were carried out. It was found that only a trace of chiral homopolymer could be produced because of a large steric hindrance between ABMA monomers. The steric hindrance can be released by introducing a suitable comonomer as a low steric hindrance spacer into the polymer backbone. Monomer reactivity ratios for poly(ABMA-co-methyl methacrylate) and poly(ABMA-co-styrene), and resonance stabilization and polarity values for ABMA were also estimated.
