ABSTRACT:
An improved chlorinated hydrocarbon is provided which is uniquely compatible with polysulfide rubber sealant formulations when incorporated as a plasticizer therein. Certain paraffins or alpha-olefins and blends thereof when chlorinated to selected final chlorine contents are compatible with polysulfide rubber sealant formulations while still maintaining the necessary low viscosity and volatility when incorporated as a plasticizer therein. The improved plasticizers are not subject to significant heat loss. Modified polysulfide rubber sealant formulations are disclosed which incorporate as a plasticizer the improved chlorinated hydrocarbon, and which are useful as glass or window sealants, particularly as glass or window sealants between the panes of a thermal pane or multi-pane insulating window structure. The improved plasticizers are non-fogging in polysulfide rubber formulations and are not subject to significant heat loss.
