含聚合物的疏水乳液及其制备方法

Hydrophobic emulsions containing polymers and process for obtaining same
摘要：
An emulsion comprising polymers and method for making same is provided. The polymers consist of the following monomers: (a) 20 to 55% by weight acrylic and/or methacrylic acid; (b) 40 to 80% by weight C1-C4 alkyl (meth)acrylates; (c) 1 to 40% by weight of a maleic acid ester according to general formula (I) R2OOC—CH═CH—COO(CH2CH2O)nR1  (I) wherein R1 represents a linear or branched alkyl, aryl or alkaryl radical having 8 to 22 carbon atoms, R2 represents hydrogen or (CH2CH2O)nR1 and n represents a number between 2 and 150, (d) 0 to 15% by weight of aralphatic compounds having at least one double bond in the aliphatic side chain; and (e) 0 to 1% by weight polyethylenic unsaturated cross-linking monomers, wherein the amounts of components (a) to (e) total 100% by weight.
