摘要： Polymer dispersions having solids contents of from 45 to 65% by weight are continuously produced by copolymerizing a vinyl ester, ethylene and (meth)acrylamidoalkyl sulphonic acid or (meth)acryloyloxyalkyl sulphonic acid or ammonium or alkali salt thereof under an ethylene pressure of from 5 to 120 atms, at a temperature of from 0.degree. to 60.degree.C in the presence of an anionic emulsifier and with the aid of a free radical forming agent.The polymer dispersions are suitable as pigment binders.
