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.
