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

Copolymers of 3-methoxy-4-methacryloyloxybenzal phenylimine and methyl methacrylate 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 techniques. Copolymer compositions were determined by H-1-NMR analysis. The monomer reactivity ratios were determined by the application of conventional linearization methods such as Fineman-Ross and Helen-Tudos. Gel permeation chromatography was used for determining the molecular weights ((M) over bar(n), and (M) over bar(w)) and the polydispersity index, Thermogravimetric analysis of the polymers were performed in air. The intrinsic viscosities of polymers were also discussed. (C) 1999 Elsevier Science Ltd. All rights reserved.
