The free-radical terpolymerization of maleic anhydride, styrene and acrylic monomers such as acrylonitrile, methyl acrylate and methyl methacrylate was studied. The alternating copolymerization of maleic anhydride with styrene was found to be favored in those systems. Contrary to theoretical predictions, maleic anhydride is more reactive than styrene in ternary systems. The relative reactivity of the acrylic monomers studied was found to decrease in the order: methyl methacrylate 2 methyl acrylate > acrylonitrile. In the presence of a Lewis acid, such as ZnCb or q q A l C I , , the relative reactivity of acrylic monomers increases and at the respective complexing agent concentration the copropagation of the acrylic monomer with styrene can dominate. On the basis of the results obtained, some aspects of the mechanism of alternating propagation in systems comprising an electron-donor monomer and two electronacceptor monomers are discussed. CN CN-ZnCh Acrylic monomers complexed by Lewis acids form alternating copolymers in reactions with styrene, similarly as maleic anhydride.

It is well known that electron-donating monomers such as styrene and butadiene can be copolymerized alternatingly with polar vinyl monomers such as methyl methacrylate and acrylonitrile in the presence of metal halides ~ '). With metal halides previously reported, such as alkylaluminium halides '), zinc chloride'), and stannic chloride'), the mole ratio of metal halide to polar vinyl monomer in the reaction mixture must be 0,3 -1 ,O or even higher, in order to achieve satisfactorily an alternate regulation of the resulting copolymer. Although a patent ' ) claims that quite a wide range of mole ratios (0,0005 to 10) of metal halide to polar vinyl monomer may be applied to achieve alternating copolymerization, no experimental results of the copolymerization at any mole ratio smaller than 0,2 has been described so far.
