Its Abstract below:Liquid sulfur—dicyclopentadiene (DCP) solutions at 140°C undergo bulk copolymerization where the melt viscosity and surface tension of the solutions increase with time. A general melt viscosity equation: η = η0 exp(aXbt), at constant temperature, has been developed, where η is the viscosity at time t for an S8-DCP feed composition of DCP mole fraction X; and η0 (in viscosity units), a (in time-1), and b (a dimensionless number, + ve for X < 0.5 and —ve for X > 0.5) are empirical constants. The structure of the sulfurated products has been analyzed by NMR. Sulfur noncrystallizable copolymeric compositions have been obtained as shown by thermal analysis (DSC). Dodecyl polysulfide is a viscosity suppressor and a plasticizer for the S8-DCP system.
