AQUEOUS POLYACRYLATE COPOLYMER DISPERSIONS WITH HIGH OH GROUP CONTENT |
摘要 |
The present invention relates to aqueous secondary copolymer dispersion comprising a copolymer (P) synthesized from a mixture of free-radically polymerizable monomers (M) comprising: (M1) cycloaliphatic esters of acrylic and/or methylacrylic acid; (M3) hydroxy-functional, free-radically polymerizable monomers; (M4) carboxyl-functional, free-radically polymerizable monomers and (M5) hydroxyl- and carboxyl-free (meth)acrylic esters having C1 to C12 hydrocarbon radicals in the alcohol moiety and/or vinylaromatics, wherein the mixture further comprises polyols (PO) selected from the group of polyester polyols and/or polycarbonate polyols, the polyols having an average hydroxyl group functionality of at least 2. The invention also relates to a method for the production of such a dispersion, to the use of the dispersion as a coating and as a binder in 2K polyurethane coatings. |
