Abstract: The present invention discloses polythiol compositions containing sulfur-containing compounds with carbamate groups, and to methods for producing such polythiol compositions. These polythiol compositions can be synthesized via the reaction of an isocyanate with an allyl ether alcohol, followed by thiolation with H2S, and these polythiol compositions are often used in formulations for adhesives, paints, and coatings.

Abstract: The application discloses thiol ester molecules and ?-hydroxy thiol ester molecules having a thiol group located on one of the final two carbon atoms in a carbon chain or a terminal or ?-hydroxyl groups, respectively. The disclosed thiol ester molecules and or ?-hydroxyl thiol ester molecules es may be made from unsaturated ester molecules having one or more terminal alkene groups. The disclosed techniques also provide methods for making unsaturated ester molecules having one or more terminal alkene groups by the metathesis of unsaturated esters having one or more internal carbon-carbon double bonds (e.g. natural source oils). The thiol ester molecules or ?-hydroxy thiol ester molecule may be used in reactions with isocyanate monomers, epoxide monomer, or material having multiple alkene groups to make sealants, coatings, adhesives, and other products.

Abstract: Aminoplast-polythiol compositions resulting from the contact product, or cured reaction product, of an aminoplast resin composition and a polythiol composition are disclosed. Typically, the polythiol composition contains thiol ester molecules having an average of two or more thiol groups per molecule. Methods for preparing the aminoplast-polythiol compositions, methods for using the aminoplast-polythiol compositions to produce coatings and to coat substrates, and coatings and other articles produced using these aminoplast-polythiol compositions also are described.

Abstract: Disclosed are copolymers of cyclic esters, e.g., caprolactone, and cyclic formals of substituted or unsubstituted diols, e.g., 1,3-dioxepane. The copolymers can provide a low melting temperature rendering them liquids at room temperature. Elastomeric polyurethanes prepared from such copolymers can exhibit a low Tg transition and good resistance to hydrolysis and oxidation. The copolymers are particularly useful for elastomers, coatings, adhesives, inks or binders requiring low temperature flexibility and good resistance to hydrolysis and oxidation.

Abstract: Sulfonate-functional polyester polyols are derived from reactants comprising an unsaturated polycarboxylic acid or derivative thereof, a polyol, a lactone, and a sulfonating agent. The unsaturated polycarboxylic acid or derivative is substantially free of sulfonate functionality, thereby providing sulfonate-fimctional polyester polyols having low color. The sulfonate-functional polyester palyols are suitable for use, for example, in the manufacture of water-dispersible polyurethanes and polyurethanes used as dispersants for particulate materials, for example, in magnetic recording media.

Abstract: A process for crosslinking a polymer containing hydroxyl groups which process comprises:(a) forming a mixture of said polymer and crosslinking amount of a poly(alpha, beta-alkenylcarboxylate), and(b) maintaining the mixture at conditions under which the polymer cures by reaction of the hydroxyl groups of the polymer with the poly(alpha, beta-alkenylcarboxylate) to produce a crosslinked polymer.
