Abstract:

The polymerization and copolymerization with styrene of a series of unsymmetrically B-p-vinylphenyl-N-methyl, and N-phenyl borazines R3R2 2B3N3R13 R1 methyl, phenyl, R2 methyl phenyl, R3 p-vinylphenyl has been studied. The polymerization of these monomers yielded both tractable and crosslinked materials. The polymers obtained were characterized by 1H and 13C NMR spectroscopy, elemental analysis, gel permeation chromatography and thermogravimeteric analysis. The reactivity ratios for the copolymerization reaction were calculated by the Mortimer-Tidewell method.
