Abstract
Poly (NPNA) has been synthesized from 4-nitrophenylmethacrylate (NPMA) in 2 -butanone using BPO as a free radical initiator. Copolymers of NPMA and BMA [poly(NPMA-co-BMA)] have also likewise been obtained. The polymers have be en characterized by IR, H-1 NMR and C-13 NMR spectral studies. The weight a verage molecular weights of the polymers lie in the range (4.1-5.2) x 10(4) while the number average molecular weights are found to be in the range (2 -2.8) x 10(4). The monomer reactivity ratios for NPMA-BMA copolymers and Q- e values for NPMA have been determined. TG and DSC studies indicate a rando m arrangement for the copolymers with thermal decomposition occurring in tw o stages.
