  • Halogen-free, deposit-control fuel additives comprising a hydroxypolyalkene amine, and a process for its production
    Patent number: 6262310
    Abstract: A halogen-free hydroxypolyalkene amine composition and a process for production thereof is disclosed. The halogen-free composition is made by epoxidizing polyalkene to form an epoxy intermediate which is subsequently reacted with an excess of an amine compound. Generally, the end product composition contains a plurality of different types of hydroxypolyalkene amines. Such compositions are useful as deposit-control fuel additives.

  • Chlorinated hydrocarbons and improved rubber sealant compositions incorporating same
    Patent number: 4189408
    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.

  • Chlorinated hydrocarbons and polysulfide rubber sealant compositions incorporating same
    Patent number: 4189407
    Abstract: An improved chlorinated hydrocarbon is provided which is uniquely compatible with polysulfide rubber sealant formulations when incorporated as a plasticizer therein. Paraffins or alpha-olefins 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.
