Naphthalene was polymerized by use of anhydrous aluminum chloride. The polynaphthalene formed was soluble in various organic solvents. The molecular weight determination suggested that the average degree of polymerization was six. The NMR spectrum indicated the presence of non-aromatic hydrogens, and the elemental analysis roughly corresponded with (C10H8)n. The reactions of the polymer was examined such as hydrogenation, bromination, thermal dehydrogenation, chloromethylation and epoxidation.

t-Butylmagnesium chloride was found to initiate the polymerization of vinyl chloride efficiently at −22–30°C. The best solvent was diethyl ether, but the degree of polymerization was the highest when no solvent was used (\barPn=1940 at 20°C). The apparent activation energy for the rate of polymerization was 13.2 kcal/mol and the frequency factor was 9.06×104. The rate of polymerization, Rp, was equal to const. ×[VC]3.90×[t−BuMgCl]1.98. Isopropylmagnesium bromide initiated the polymerization with less efficiency, and phenylmagnesium bromide was completely ineffective. Vinyl chloride and styrene were copolymerized in ether by t-butylmagnesium chloride at 30°C. The mole % styrene included in the copolymer was considerably different from those obtained by benzoyl peroxide at 48°C or by di-t-butylperoxy oxalate at 30°C.
