Radical Copolymerizability of 3-Ethylideneacetylacetone and Diethyl Methacryloylmalonate

Abstract

3-Ethylideneacetylacetone (EAA) and diethyl methacryloylmalonate (MMD) have been copolymerized with styrene (St) and acrylonitrile (AN). The copolymerizations were carried out at 60°C. The monomer reactivity ratios of each of these monomer pair were determined. The reactivity ratios were:
From these results, the Q and e values for EAA and MMD were calculated as follows:
Q=0.028, e=0.91 for EAA
Q=1.45, e=0.97 for MMD
