“…Allyl halides, 7-chloro-1-octene, and 3-chlorocyclohexene give no or low molecular weight polymer due to dehydrohalogenation. ,,, Bacskai has also noted that 6-chloro- and 6-bromo-1-hexene are not polymerized and suggests that monomer dehydrohalogenation is accelerated in this case by a double-bond-assisted, six-membered ring intermediate. A few scattered reports exist describing Ziegler−Natta polymerization of vinyl chloride, − perfluorinated monomers, chloroprene, and halostyrenes …”

Complexes of aluminum alkyls with Lewis bases catalyze the polymerization of vinyl chloride. Triethylaluminum is most effective, but other compounds of type R3Al, R2AlCl, R2AlH, and LiAIR4 are operable. Dialkylmagnesiums are active, but Grignard reagents, as well as a number of other metal alkyls are inactive. Among Lewis bases, tetrahydrofuran (THF) and tetrahydropyran give the best yields of poly(vinyl chloride). Oxygen bases, such as ethers and esters, are more effective than nitrogen bases, e.g., tertiary amines. Cyclic compounds are better than acyclic ones. The polymerization occurs in a variety of hydrocarbon, chlorinated hydrocarbon, or ether solvents, but especially well in CCl4. Radical polymerization is probably initiated through the reaction R3Al:Base + CCl4 → R2AlCl: Base + R + Cl3C., to form trichloromethyl radical.
