Abstract

The process is for production of sterically stabilised aqueous polymer dispersions based on styrene and 1-8 carbon alkyl (meth)acrylate(s), which are free from emulsifier and have increased mortar stability. The process comprises adding 1-20 wt.% 1-8 C hydroxyalkyl (meth)acrylate(s) with respect to total monomers in the presence of a water-soluble protective colloid and a free radical initiator or an initiator system consisting of a free radical initiator and a water-soluble reducing agent. Also claimed are (a) powder that is redispersible in water, prepared from these dispersions, and (b) a method of producing the powder.
