    摘要： Aqueous polyacrylate dispersions comprising hydrophobic co-solvents are provided. The dispersions are prepared from copolymers P) which are comprised of I) a hydroxy-functional, hydrophobic polymer containing as structural monomers Ia) (meth)acrylic acid esters having from C1- to C18-hydrocarbon radicals in the alcohol part and/or vinyl aromatic compounds and/or vinyl esters and Ib) hydroxy-functional monomers; and II) a hydroxy-functional, hydrophilic polymer containing as structural components IIa) (meth)acrylic acid esters having from C1- to C18-hydrocarbon radicals in the alcohol part and/or vinyl aromatic compounds and/or vinyl esters, IIb) hydroxy-functional monomers and IIc) acid-functional monomers, and as solvents C) one or more solvents selected from the group consisting of hydrophobic, water-immiscible hydrocarbons having an initial boiling point of from 170° C. to 250° C. and a dry point of from 200° C. to 280° C., to a process for their preparation and to their use as binders for the production of blister-free coatings.

    摘要： A process for preparing copolymer dispersions that includes subjecting A) one or more vinyl monomer mixtures containing a) OH-free (meth)acrylic esters and/or vinylaromatics, b) hydroxy-functional vinyl monomers and/or hydroxy-functional (meth)acrylic esters, c) ionic and/or potentially ionic monomers capable of free-radical copolymerization, and d)optionally further monomers, other than the compounds of components a)–c), capable of free-radical copolymerization; to free-radical polymerization in the presence of e) compounds according to formula (I) where R1 is an aliphatic, araliphatic or aromatic radical having 1 to 18 carbon atoms, R2 is H or CH3, R3, R4 are identical or different aliphatc radicals having 1 to 7 carbon atoms and n is 1 to 4; and subsequently dispersing the resultant copolymer B) before or after addition of a neutralizing agent C) in water. The resulting dispersions can be used to coat substrates.
