The copolymerizations of acrylonitrile and methyl acrylate with propylene, isobutylene, butadiene, styrene, and vinyl chloride and the copolymerizations of methacrylonitrile and methyl methacrylate with propylene in the presence of ethylaluminium dichloride as the complexing agent were studied. When the polar vinyl monomer is not completely complexed by ethylaluminium dichloride in the copolymerizations of acrylonitrile with propylene, isobutylene, and vinyl chloride, and in those of methacrylonitrile and methyl methacrylate with propylene, copolymers rich in polar vinyl monomer were found. In the copolymerization of acrylonitrile with propylene, the polar vinyl monomer content in the copolymer was found to increase with decreasing mole ratio ethylaluminium dichloride/acrylonitrile in the monomer feed.

The copolymerization of vinyl chloride (VC) and methyl acrylate (MA) in the presence of ethylaluminium compounds (C2H5AlCl2, (C2H5)2AlCl, and (C2H5)3Al) at low ethylaluminium compound (EAC)/MA mole ratios was investigated. An alternating copolymer was produced in this reaction when an excess of VC in the initial monomer feed was used. The addition of dibenzoyl peroxide (BPO) to the systems containing EAC resulted in an increase of the alternating copolymer yield. In polymerization systems containing EAC resulted in an increase of the alternating copolymer yield. In polymerization systems containing EAC combined with VOCl3 an enhancement of the alternating copolymer yield and formation of VC‐rich copolymers were observed. In the polymerization system with (C2H5)3AlVOCl3 a VC‐rich copolymer was the main product. It was concluded that VC‐rich copolymers are formed in the random radical copolymerization which occurs when most of EAC is complexed by the alternating copolymer chain. The structure of alternating and VC‐rich copolymers was studied in detail by means of 13C NMR spectroscopy.

Investigations of the copolymerization of acrylonitrile, methacrylonitrile, methyl acrylate, methyl methacrylate, acrylic acid, acryloyl chloride, methyl vinyl ketone, and acrolein with styrene, and of acrylonitrile with acenaphthylene and 1,3‐cyclopentadiene in the presence of Lewis acids as catalysts have been carried out. It was found that the free‐radical alternating copolymerization and ionic copolymerization or homopolymerization reactions can proceed in these systems. The yield of the competitive free‐radical and ionic reactions was related to the type of monomers and strength of the Lewis acid. The mechanism of the catalytic effect of Lewis acids in the reactions studied is discussed.
