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: Methods are provided for using a molecular sieve catalyst for dewaxing formed using a synthesis mixture comprising a morphology modifier. The catalyst may be used, for example, for production of a lubricant base stock. For example, ZSM-48 crystals formed using the morphology modifier (and/or formulated catalysts made using such crystals) can have an increased activity and/or can provide an improved yield during catalytic dewaxing of lubricant base stocks.
