Abstract: Hot melt adhesives may comprise linear alpha olefins (LAOs) or LAO-derived compounds as an at least partial replacement for paraffinic white oil diluents. Such adhesive compositions may comprise an ethylenically unsaturated polymer or copolymer, a tackifier, and a diluent. The diluent may comprise at least one of: one or more C18+ linear alpha olefins (LAOs) having a kinematic viscosity of about 4 cSt or less at 135° C.; one or more LAO dimers formed from one or more C18+ LAOs, the one or more LAO dimers having an internal olefin and a kinematic viscosity of about 6 cSt or less at 135° C., or one or more paraffinic hydrocarbons having an even carbon number distribution and formed through dimerization of one or more C18+ LAOs and subsequent reduction. The one or more paraffinic hydrocarbons may have a kinematic viscosity (ASTM D-445) of about 4 cSt to about 8 cSt at 135° C.

Abstract: Blending of polyvinylchloride (PVC) and other rigid polymers may be facilitated using lubricant compositions comprising linear alpha olefins (LAOs) or compounds derived from LAOs. PVC blending methods may comprise: combining PVC and a lubricant composition to form a mixture, and blending the mixture to form a lubricated PVC blend, in which the mixture contains an effective amount of the lubricant composition to provide a fusion temperature for the lubricated PVC blend of about 190° C. or below as determined by torque rheometry at 65 rpm. The lubricant composition may comprise one or more C18+ linear alpha olefins (LAOs) having a kinematic viscosity of about 4 cSt or less at 135° C., or one or more LAO dimers formed from the one or more C18+ LAOs, the one or more LAO dimers having an internal olefin and a kinematic viscosity of about 6 cSt or less at 135° C., or reduced LAO dimers.

Abstract: Rubber blends may comprise at least one rubber compound, and at least one wax mixed with the at least one rubber compound, and wherein the at least one wax comprises an unsaturated wax. Suitable unsaturated waxes may include, but are not limited to C18+ linear alpha olefins (LAOs), LAO dimers formed from C18+ LAOs and having an internal olefin, or any combination thereof. The C18+ LAOs may be C20-C24 LAOs or C24+ LAOs. The rubber blends may be used in forming various rubber articles and in forming at least a portion of a tire, such as a tire sidewall containing a vulcanized rubber blend.
