Kinetics of Free Radical Polymerization of N-Substituted Amides and Their Structural Implications

الملخص EN

Two N-substituted amides (N-acryloyl morpholine and N-methyl-N-vinylacetamide) were polymerized in different solvents using radical initiator.

The tacticity of obtained polymers was determined by 400 MHz 1H-NMR and 13C-NMR.

At a given temperature, the syndiotacticity increased with increasing the solvent polarity.

This solvent effect may be related to the hydrogen bonding interaction among solvent, monomer, and/or growing species.

A peculiar aspect regards the steric hindrance at the nitrogen atom.
