1,3,5-Trivinyl-2,4,6-trichlorobenzene has been prepared and its copolymerization, at low weight percentages, with styrene has been studied by following the change in viscosity of the polymerizing systems as a function of time. The copolymerization was studied as a function of the concentration of the trivinyl compound (0.5-2 weight per cent) at two temperatures and two benzoyl peroxide concentrations. The gelation times and per cent styrene polymerized at gelation were estimated. In addition, the copolymerization of 1,3,5-trivinyl-2,4,6-trichlorobenzene with styrene was compared with that of 1,4-divinyl-2,3,5,6-tetrachlorobenzene and 1,3-divinyl-2,4,5,6-tetrachlorobenzene, both with styrene. The infrared and ultraviolet spectra of the three cross-linking agents were determined. The ultraviolet spectrum of 1,4-divinyl-2,3,5,6-tetrachlorobenzene provides a basis for explaining its greater reactivity in copolymerization with styrene.
