ABSTRACT:
Low molar mass copolymers which can be prepared by reacting one or more glycidyl esters of saturated aliphatic monocarboxylic acids having a tertiary or quaternary .alpha. carbon atom, and at least two unsaturated copolymerizable monomers of which at least one has at least one COOH group, under the conditions of a free-radical copolymerization, whereby the weight-average molar mass of the copolymers is below 3500 g/mol and the proportion of branched side chains in the copolymer is at least 20% by mass are disclosed. Also disclosed are methods of making these copolymers and the use thereof in binder and coating systems.
