Polymerization of Alpha-(N-vinylformamidomethyl)acrylates: Cyclopolymers from Non-Symmetric Monomers
Polymers and High Performance Materials
t-Butyl alpha-(N-vinylformamidomethyl)acrylate (tBVFA) and ethyl alpha-(N-vinylformamidomethyl)acrylate (EVFA) were synthesized from t-butyl alpha-bromomethylacrylate and ethyl alpha-chloromethylacrylate, respectively. tBVFA was found to cyclopolymerize at 120 degrees C in DME DMSO, and 1,2-dichlorobenzene at solvent: monomer ratios of 10 : 1 vol. wt. Molecular weights for poly(tBVFA) ranged from 10 000 to 13 000 as estimated by size-exclusion chromatography. At lower solvent monomer ratio (1:1), and at lower temperature (71 degrees C), crosslinking occurred. EVFA was found to cyclopolymerize, but only in DMF at 122 degrees C and at a 10: 1 solvent:monomer ratio.
