| titleOfInvention | Hydroxyl groups-containing copolymers based on vinyl ester, vinyl aromate and hydroxyl alkyl ester monomers, process for their preparation and their use in coating compositions |
| abstract | The invention concerns hydroxyl group-containing copolymerizates with an OH number of 50 to 200 mg KOH/g and a mean molecular weight (numerically) of 1500 to 6000, which can be produced by radical solution polymerization at temperatures of 130 to 200 DEG C from 5 to 25 wt.% of vinyl ester monomers, 10 to 50 wt.% of vinyl aromatic monomers, 10 to 50 wt.% of hydroxyalkyl ester monomers and possibly other monomers. The vinyl ester monomer is taken and the other monomers are added within a monomer addition time-interval equal for all monomers, as follows: i) the quantity of acrylate monomers added per unit time is constant; ii) the quantity of vinyl aromatic monomer added during the first third of the monomer addition time-interval is equal to 15 to 30 wt.%, preferably 18 to 26 wt.%, in the second third 25 to 40 wt.%, preferably 30 to 38 wt.%, and in the third third 35 to 60 wt.%, preferably 40 to 50 wt.%, referred to the total amount of vinyl aromatic monomer. Also described are processes for producing the copolymerizates and their use in coating agents. |
