Abstract
AbstractPhenyl methacrylate (PMA), as well as its 2‐ and 4‐methoxy analogs (2‐MeOPMA and 4‐MeOPMA, respectively) were polymerized by free radical and anionic polymerization reactions. On anionic polymerization in toluene termination reactions occurred, and polymers were obtained only from PMA and 4‐MeOPMA. Polymers with relatively narrow molecular weight distributions were formed on anionic polymerization in tetrahydrofuran.The steric structures of the polymers were determined from 100 MHz NMR spectra. Polymers obtained by free radical polymerization were found to be predominantly syndiotactic. Anionic polymerization in toluene produced highly isotactic polymers, while the use of tetrahydrofuran as a solvent gave syndiotactic polymers. Glass transition temperatures of the syndiotactic polymers were generally higher than those of the isotactic ones.
