Kinetic Investigations of the Copolymerization of Ethyl Acrylate and Acrylonitrile with Maleic Anhydride

Abstract
The copolymerization of maleic anhydride with ethyl acrylate (I) in 1,2-dichloroethane and with acrylonitrile (II) in acetone at 50°C with AIBN as initiator was investigated. The v Br curves show no maximum. The v Br values and molecular weights decrease with the molar fraction xM An. The r values for both pairs of monomers were determined. For I, k St, k z, and f were also ascertained and v Br curves calculated, and they are compared with the experimental results.
