Abstract: Polyurethane elastomers formed from prepolymers derived from copolyester polyols. The copolyester polyols have segments derived from one or more polyesters and caprolactone or polycaprolactone. The polyurethane elastomers have good hardness stability at temperatures ranging from 0° C. to 30° C. and preferably have good hydrolytic stability.

Abstract: A rebound resilient golf ball having an core layer or layers with one or more cores, a scuff resistant cover of thermoplastic polyurethane surrounding the core layer or layers, and optionally a mantle layer positioned between the cover and the core layer or layers. The cover is made from a dendritic thermoplastic polyurethane that includes an isocyanate monomer and a hyper branched polyol, optional additional polyols, and one or more chain extenders. An optional mantle layer may also be made of thermoplastic polyurethane, particularly a dendritic thermoplastic polyurethane.

Abstract: Disclosed herein is a paint composition comprising a hydroxyl group containing resin (A), comprising structural units based on 2,2-dimethylolalkanoic acid, having a hydroxyl group value of from 200 to 400 mgKOH/g, and comprising less than 25 weight % in the resin solid fraction of structural units based on a lactone compound; a hydroxyl group containing resin (B), having a hydroxyl group value from 50 to 200 mgKOH/g, and comprising from 25 to 75 weight % in the resin solid fraction of structural units based on a lactone compound; and a crosslinking agent (C) comprising at least two OH-reactive functional groups per molecule; wherein the resin solid fraction weight ratio (A)/(B) of the hydroxyl group containing resin (A) and the hydroxyl group containing resin (B) is from 90/10 to 10/90.

Abstract: A 2K basecoat clearcoat system includes a solvent borne basecoat having a low Tg branched polyester polyol, optionally, a high Tg, high molecular weight thermoplastic resin, and a hardener that includes an isocyanate functional material suitable for crosslinking the polyester polyol, and optional thermoplastic resin. The solvent borne clearcoat composition includes a low Tg linear or branched polyester polyol, at least one other multi-functional polyol, and an isocyanate functional material suitable for crosslinking the polyester and multi-functional polyols.

Abstract: A molding composition is provided that includes a thermoset cross-linkable polymeric resin, a fibrous filler and a thickener system. The thickener system includes an amine and an isocyanate that are reactive to form a polyurea. The polyurea is operative to thicken the molding composition formulation prior to polymeric resin thermoset with superior properties relative to conventional thickener systems. A molded article produced from a cross-linked thermoset polymeric resin containing fibrous filler and a polyurea present from 1 to 5 total weight percent of the article either forms an interpenetrating network between the resin and the polyurea or the resin and polyurea crosslink upon resin thermoset to further strengthen the resulting article. An alkali earth oxide or hydroxide simultaneously thickens through interaction with carboxylate functionality of the cross-linkable resin to provide a superior viscosity build and humidity tolerance.

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: A resin composition having excellent impact resistance and heat resistance, comprising a poly-3-hydroxybutyrate, and a core-shell latex rubber comprising an acrylic rubber and/or silicone-acrylic rubber copolymer as a core component and polymethyl methacrylate as a shell component, or a specific thermoplastic polyurethane, is disclosed. The resin composition satisfies the following requirements (c) and (d): (c) a crystallization temperature when heated from room temperature to 180° C. at a temperature rising rate of 80° C./min by a differential scanning calorimeter, maintained at 180° C. for 1 minute, and then cooled at a temperature lowering rate of 10° C./min is 110-170° C.; and (d) a weight average molecular weight (Mw) in terms of polystyrene conversion when a chloroform soluble component is measured with a gel permeation chromatography is 100,000-3,000,000.

Abstract: A polyester binder resin for a toner that excels in low-temperature fixing properties, offset resistance, development durability, long-term storability, electrification properties, pulverizability, etc.; and a toner containing the same. The binder resin for a toner is comprised of a polyester resin and, dispersed therein, a wax having a substituent selected from among a substituent of aromatic structure (representative example thereof is a group derived from a styrene compound), a carboxyl group and a hydroxyl group, or comprised of a polyester resin having the above wax introduced in the structure thereof. The toner containing the above binder resin for toner exhibits excellent capability in not only, as fundamental performance of toner, low-temperature fixing properties and offset resistance but also development durability, antiblocking properties and pulverizability.
