Copolymerization of 3-methoxy-4-methacryloyloxybenzal phenylimine with methyl methacrylate

Copolymers of 3-methoxy-4-methacryloyloxybenzal phenylimine and methyl meth acrylate were synthesized with different feed ratios in ethyl methyl ketone solution at 70 degrees +/- 1 degrees C using benzoyl peroxide as initiator . The copolymers were characterized by IR and H-1-NMR spectroscopic techniq ues. Copolymer compositions were determined by H-1-NMR analysis. The monome r reactivity ratios were determined by the application of conventional line arization methods such as Fineman-Ross and Helen-Tudos. Gel permeation chro matography was used for determining the molecular weights ((M) over bar(n), and (M) over bar(w)) and the polydispersity index, Thermogravimetric analy sis of the polymers were performed in air. The intrinsic viscosities of pol ymers were also discussed. (C) 1999 Elsevier Science Ltd. All rights reserv ed.
