Abstract: Embodiments of the invention generally relate to polyols having resistance to hydrocarbons and articles made therefrom. More specifically, embodiments of the invention generally relate to hydrophilic polyester-polycarbonate polyols having resistance to hydrocarbons at high temperatures and articles made therefrom. The novel hydrophilic polyester-polycarbonate polyols described herein may be used in adhesive or elastomer applications requiring enhanced oil and/or diesel resistance. The disclosed polyols are liquid at room temperature, which facilitates processing into polyurethane products As described herein, an elastomer made from such hydrophilic polyester-polycarbonate polyols and methylene diphenyl diisocyanate (MDI) retained >90% of tensile strength after 500 hours ageing at 121 degrees Celsius. A comparative example made from a polyester polyol retained 50% of tensile strength under similar conditions.

Abstract: An object of the present invention is to provide a golf ball comprising a core and a cover, wherein the cover is made from a cover composition containing, as a resin component, a thermoplastic polyurethane (A) and a polyisocyanate mixture (B) in which a polyisocyanate (b-1) having at least three isocyanate groups is dispersed in a thermoplastic resin (b-2) which does not substantially react with an isocyanate group; and wherein the cover composition has a slab hardness of more than 60 and not more than 75 in Shore D hardness, and the cover has the thickness of 2.5 mm or less.
Abstract: The present invention relates to polyester polyols with low functionality and a process for their production, to prepolymers prepared from these polyester polyols and a process for their production, and to polyurethanes prepared from these polyester polyols and/or from these prepolymers, and to processes for their production. These polyester polyols are produced in a two-step process. In the second step of this two-step process, one or more cyclic ester monomers is reacted with one or more polyester polyols at low temperatures.
Abstract: Process for the production of a polyester by the polycondensation of a mixture comprising isoidide, and a dicarboxylic acid or dicarboxylic acid anhydride, wherein the reaction is performed in the melt of the monomers and wherein these monomers are not activated. The polyesters based on one or more of the three isomers of dianhydrohexitol, being isosorbide, isomannide and isoidide, have properties which makes them suitable to be used in powder coatings, toner compositions as well as engineering plastics. The polyesters include a polyester according to the following formula, wherein n ranges from 3 to 300.
