Abstract: A polyester is useful as a high viscosity base fluid. A method for its preparation involves isomerizing an alpha-olefin, epoxidizing an internal olefin, reacting an internal epoxide, and isolating the polyester. Lubricant compositions can contain such polyesters and the compositions are useful as automatic transmission fluids, manual transmission fluids, continuously variable transmission fluids, gear oil formulations, industrial gear oil formulations, axle fluid formulations, dual clutch transmission fluids, dedicated hybrid transmission fluids, or as hydraulic oils.

Abstract: A polyester is useful as a high viscosity base fluid. A method for its preparation involves epoxidizing an alpha-olefin, reacting the alpha-epoxide or diol with a saturated linear aliphatic dicarboxylic acid, and isolating the polyester. Lubricant compositions can contain such polyesters and the compositions are useful as automatic transmission fluids, manual transmission fluids, continuously variable transmission fluids, gear oil formulations, industrial gear oil formulations, axle fluid formulations, dual clutch transmission fluids, dedicated hybrid transmission fluids, or as hydraulic oils.

Abstract: The present invention relates to an additive manufacturing process using a composition comprising the reaction product of a polyester polyol and a compound comprising at least one functional group that can react with a hydroxyl-group of the polyester polyol and at least one further functional group, selected from acrylate- or methacrylate-group, wherein the polyester polyol is based on at least one organic acid comprising at least two carboxyl groups or its anhydride and at least one polyol comprising at least two hydroxy-groups, wherein the reaction product has a glass transition temperature Tg of below 23° C., wherein the composition optionally further comprises a photoinitiator, as a photopolymerisable material in.

Abstract: The present invention relates to a method in which an adhesive bond is brought into contact with a supercritical fluid, characterized in that the adhesive bond is based on one or more adhesives comprising crosslinked polymers, where the crosslinked polymers have at least one oxygen atom in the polymer chain and have been crosslinked via urethane bridges or —O—CH2—CH(OH)—CH2—O— bridges or molecular chains having corresponding bridges, and in that after bringing the adhesive bond into contact with the supercritical fluid, at least one of the parameters pressure, volume, amount of substance or temperature is changed such that the fluid transitions from the supercritical state into a different state, and also to the use of this method as at least a substep in a method for separating adhesive bonds of components.

Abstract: What are described are compositions for production of polyurethane foam, comprising at least an isocyanate component, a polyol component, optionally a catalyst that catalyzes the formation of a urethane or isocyanurate bond, optionally blowing agent, wherein the composition comprises block copolymers based on OH- or amino-functionalized polyolefins and polyesters that act as foam stabilizer.
