PROCESS FOR PREPARING COPOLYMERS CONTAINING OH GROUPS, AND THEIR USE |
摘要 |
A process for the preparation of copolymers containing hydroxyl groups by radical reaction of (A) 10 to 30% by weight of at least one glycidyl ester containing 12 to 14 carbon atoms, of an aliphatic saturated monocarboxylic acid with a tertiary or quaternary alpha -carbon atom; and (B) 90 to 70% by weight of at least two unsaturated copolymerisable monomers, at least one of which contains at least one carboxyl group, wherein component (A) is introduced first to a reaction zone and is then reacted at a temperature of at least 140 DEG C. with component (B) and a radical initiator, the component (B) containing a monomer having carboxyl groups, wherein for the preparation of low-viscosity copolymers component (A) is reacted at 140 to 200 DEG C. by substance polymerisation until a degree of reaction of at least 95% is achieved, the component (B) containing at least 3.3% by weight of the monomer having carboxyl groups, and an article coated with a product of said process. |
