Abstract

Laser‐initiated polymerization of charge transfer monomer complexes has been investigated using an argon ion laser. The influence of solvents, monomer feed ratio, and irradiation time on the copolymer yield and composition was evaluated. The polymer yield was found to be directly proportional to the irradiation time and the molar concentration of maleic anhydride in the monomer feed. An enhanced rate of polymerization was obtained by substituting electron donating groups in the donor monomer. Polymerization, initiation, and propagation mechanisms, via charge transfer complexes, have been discussed. Comparison of laser‐induced polymerization with UV‐induced polymerization suggests that laser initiation is an energy‐efficient process.

The copolymerization of maleic anhydride (MA), N-2-chlorophenyl maleimide (2-CMI) and N-a-naphthyl maleimide (a-NMI) with styrene (ST) initiated by y-radiation has been studied. The initial rate of copolymerization depends on the total concentration of the comonomers, and the rate decreases in the s
