| titleOfInvention | Hydroxyl group-containig copolymerizates based on vinyl ester monomers, vinyl aromatic monomers and hydroxyalkyl ester monomers, process for producing them and their use in coating agents |
| abstract | Copolymers containing hydroxyl groups have an OH number between 50 and 200 mg KOH / g and an average molecular weight (numerical average) between 1500 and 6000. These copolymers can be obtained by radical polymerization in solution at temperatures between 130 ° and 200 ° C from 5 to 25% by weight of vinylester monomers, from 10 to 50% by weight of aromatic vinyl monomers, from 10 to 50% by weight of hydroxylalkylester monomers and, where appropriate, d 'other monomers. The vinylester monomer is taken and the other monomers are added thereto during an equal addition time for all the monomers, as follows: i) the amount of acrylate monomers added per unit of time remains constant; ii) relative to the total amount of aromatic vinyl monomers added, the amount of aromatic vinyl monomers added during the first third of the monomer addition period is between 15% and 30% by weight, preferably between 18 % and 26% by weight, during the second third between 25% and 40% by weight, preferably between 30% and 38% by weight, and during the last third between 35% and 60% by weight, preferably between 40% and 50% by weight. Process for the production of these copolymers and their use in coating agents. |
