COMPARATIVE INVESTIGATION OF VINYL POLYMERIZATION UNDER MICROWAVE IRRADIATION

Microwave
(MW) assisted polymerization of acrylonitrile, methyl methacrylate, N-vinyl
pyrrolidone and glycidyl methacrylate was investigated and their progress has
been compared with reference to MW powers ranging 25-100W. The polymerization
afforded increasing monomer conversion (%C) up to 50W resulting in polymers
with enhanced rheoviscosity, thermal stability and particles size ranging
4.98-100.12 nm The polymers were characterized through Uv-vis, FT-IR, 1H-NMR
spectra, thermal analysis and AFM.

Key words: Microwave irradiation, Vinyl
polymerization, Spectra, Microscopy and Thermal analysis
