Soy-based high temperature products, or thermoset resins, are produced by solvent free polymerization of soy polyols and polyisocyanates at room temperature. The ratio of isocyanate equivalents to polyol equivalent used in the synthesis is greater than or equal to 3. The invented soy-based products are polyisocyanurate solid materials with excellent stability at high temperature. Heat resistance of the material is influenced by ratio of soy polyol and polyisocyanate.

Polyurethane foam-forming compositions, methods of producing polyurethane foams, polyurethane foams produced from such compositions made by such methods, as well as isocyanate-reactive compositions. The polyurethane foam-forming compositions include a polyol blend, a blowing agent composition, and a polyisocyanate. The polyol blend includes an aromatic amine-initiated polyether polyol, a saccharide-initiated polyether polyol, and an aromatic polyester polyol and has a content of —C.sub.2H.sub.4O— units of 3 to 6% by weight, based on the total weight of the polyurethane foam-forming composition. The blowing agent composition includes a hydrochlorofluoroolefin and a carbon dioxide-generating chemical blowing agent.

This invention relates to aliphatic, carbamate-functional polyester resins for use in coatings. More particularly this invention relates to aliphatic, carbamate-functional polyester resins containing 2,2,4,4-tetramethyl-1,3-cyclobutanediol (TMCD) that exhibit improved scratch resistance and acid etch resistance when formulated into 2K automotive clearcoats. These carbamate-functional polyesters can be used as the sole resin in the clearcoat binder or in combination with other carbamate-functional acrylic resins and/or hydroxyl-functional acrylic and polyester resins.

A method of preparing a polyisobutylene-based polyurethane for making heart valves is disclosed, wherein the method includes providing a polyisobutylene (PIB) polymer, freshly distilling a diisocyanate compound to create a freshly distilled diisocyanate and providing a chain extender. When the polyisobutylene polymer, the freshly distilled diisocyanate, and the chain extender are combined together by mixing, the created polyisobutylene-based polyurethane exhibits a higher number average molecular weight, a higher ultimate strength, a higher elongation, and a greater toughness than a polyisobutylene-based polyurethane made without a freshly distilled diisocyanate, which makes the polymer particularly useful as a bioprosthetic heart valve.

Provided is a latent curing agent, including: porous particles supporting an aluminum chelate compound; and a coating film over surfaces of the porous particles, the coating film containing an aluminum chelate compound and a polymer that contains at least one of a urea bond and an urethane bond, wherein a content of an active aluminum chelate compound is 20% by mass or greater.
