<p>An improved chlorinated hydrocarbon is provided which is uniquely compatible with polysulfide rubber sealant formulations when incorporated as a plasticizer therein. Paraffins or alphaolefins containing from 16 to 20 carbon atoms per molecule or mixtures or blends of paraffins or alpha-olefins containing 16 to 20 carbon atoms per molecule are chlorinated to a final chlorine content of from between 52 and 58 weight percent chlorine. The chlorinated hydrocarbons are compatible with polysulfide rubber sealant formulations while still maintaining the necessary low viscosity and volatility when incorporated as a plasticizer therein. A modified polysulfide rubber sealant formulation is disclosed which incorporates as a plasticizer the improved chlorinated hydrocarbon, and which is useful as a glass or window sealant. The improved plasticizer is non-fogging in a polysulfide rubber formulation.</p> |
