| 摘要 |
<p>The present invention relates to an emulsion polymer comprising at least one (meth)acrylate segment which comprises 1% to 30% by weight of units derived from (meth)acrylates which in the alkyl radical have at least one double bond and 8 to 40 carbon atoms, 0.1% to 10% by weight of units derived from monomers containing acid groups, and 50% to 98.9% by weight of units derived from (meth)acrylates having 1 to 6 carbon atoms in the alkyl radical, based in each case on the weight of the (meth)acrylate segment, the emulsion polymer having a particle radius of at least 50 nm.</p> |
