Use of aqueous polymer dispersions for modifying mineral building materials

摘要

Aqueous polymer dispersions whose polymer is composed of up to <5% by weight of (meth)acrylic acid, up to <5% by weight of (meth)acrylamide and from 90 to 97.5% by weight of other nonionic unsaturated monomers and is present as dispersed polymer particles having a weight average diameter of from 100 to 300 nm are used for modifying mineral building materials.
