Patent number: 9296860Abstract: There is described a process for producing a gel free hyperbranched polyamide polymer having primary amino groups (useful as a crosslinker). The process comprises the step of reacting at least one diamine and at least one unsaturated diester in a molar ratio of diamine to diester greater than 1 but less than 3 (preferably 2.1 to 2.9); to form the polyamide in a two stage reaction Michael addition and then amidation. The diamine in kept in excess with at least 5% of water by total weight of the diamine and diester, a reaction temperature less than the boiling point of the diamine; and is held under reduced pressure (30 mbar to 1 atms). Gelation does not occur even after substantially all ethylenic (—C?C—) double bonds; and >95% ester [—C(O)?O] groups have reacted. This violates the Flory rules which predict a gel would form based on the number of functional groups present and their degree of conversion.Type: GrantFiled: December 21, 2010Date of Patent: March 29, 2016Assignee: DSM ASSETS B.V.Inventors: Joseph Petronella Friederichs, Jacobus Adriaan Antonius Vermeulen, Marco Marcus Matheus Driessen

Publication number: 20140024770Abstract: The invention relates to an airdrying resin suitable for a coating composition characterized in that the resin is a polyesteramide prepared from: A) at least one anhydride chosen from the list containing succinic, glutaric, citraconic, itaconic or maleic anhydride or a combination of any of them, and B) at least one alkanol-amine, and C) at least one fatty acid, wherein the fatty acid is incorporated in the resin in an amount equivalent to an oil- length between 15 and 40%. This airdrying resin is both water- and solvent-soluble, having a combination of properties desirable for different types of applications. The invention relates also to a method for preparing such a polyesteramide resin, to a composition comprising at least one polyesteramide resin and a method for preparing such a composition, to a substrate fully or partially coated with this composition, a method for curing the coated substrate, the cured and coated substrate and the use of resin in various applications.Type: ApplicationFiled: September 16, 2013Publication date: January 23, 2014Applicant: DSM IP ASSETS B.V.Inventors: Rudolfus Antonius Theodorus Maria VAN BENTHEM, Joseph Petronella FRIEDERICHS
