Patent number: 11009628Abstract: The invention relates to a process of making an anti-reflective coating composition comprising the steps of 1) preparing an oil-in-water emulsion by mixing an apolar organic compound A; a cationic addition copolymer C as emulsion stabilizer; and aqueous medium of pH 2-6; at a mass ratio C/A of 0.1 to 2, to result in 1-50 mass % (based on emulsion) of emulsified droplets of average particle size 30-300 nm; and 2) providing an inorganic oxide shell layer to the emulsified droplets by adding to the emulsion obtained in step 1) at least one inorganic oxide precursor, to result in organic-inorganic core-shell nano-particles with mass ratio core/shell of from 0.2 to 25. An advantage of this process is that the dispersion of nano-particles obtained is stable under different conditions, and allows altering its concentration and solvent system, and addition of different binders and auxiliary components.Type: GrantFiled: April 10, 2019Date of Patent: May 18, 2021Assignee: DSM IP ASSETS B.V.Inventors: Michael Alphonsus Cornelis Johannes Van Dijck, Hermanus Adrianus Langermans, Jacobus Adriaan Antonius Vermeulen

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
