Reactions of polymerization of cyclohexene, vinylcyclohexene, and unsaturated compounds of synthine under pressures up to 4,000 kg. per cm.2 and at temperatures up to 300°, 350°, and 360°, respectively, were studied. The polymerization of synthine (n20D 1.3969; boiling up to 150°; d20=0.7143; I no. 80.0) leads to the formation of oily products with a gently sloping viscosity-temperature curve. The oily product obtained in the experiment in which P=4,000 kg. per cm.,2 T=360°, and t=3.5 hr. was distilled under vacuum; 2 gm. were obtained, b0.5 150°-255°. The viscosity of the oil was slightly less than that of the turbine oil; n21D 1.4836. It congealed at 40°-45°.
