| 摘要 |
FIELD: chemistry.SUBSTANCE: invention refers to coating compositions containing dispersions of multi-stage polymers, to a method for producing the above dispersions and using the coating compositions. The dispersion is prepared by two-stage emulsion polymerisation the first stage of which involves carrying out a reaction of (A1) at least one (meth)acrylic acid alkyl ester with 1-4 carbon atoms, (B1) at least one vinylaromatic compound containing up to 20 carbon atoms and (C1) at least one hydroxyalkyl(meth)acrylate with 1-4 carbon atoms in the presence of at least one initiator; the second stage involves radical co-polymerisation of a co-polymer (A2) prepared at the first stage with at least one (meth)acrylic acid alkyl ester with 1-8 carbon atoms.EFFECT: compositions are used for one-component or two-component coatings applied on polymers, wood, paper or metal, or as an adhesive.21 cl, 10 ex |
