ABSTRACT OF THE DISCLOSURE An improved chlorinated hydrocarbon is provided which is uniquely compatible with polysulfide rubber sealant formu- lations when incorporated as a plasticizer therein. Certain paraffins or alpha-olefins and blends thereof when chlorinated to selected final chlorine contents are compatible with poly- sulfide rubber sealant formulations while still maintaining the necessary low viscosity and volatility when incorporated as a plasticizer therein. The improved plasticizers are not sub- ject 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 sub- ject to significant heat loss.
