    Abstract: A method for producing aqueous polymer dispersions by means of radically initiated emulsion polymerisation, in an aqueous medium, of vinyl ester and ethylene, in series-connected polymerisation reactors, wherein in a first discontinuous polymerisation phase at least some of the reactants are introduced into the first polymerisation reactor and the remainder is added in a metered fashion. The reactor is filled up to more than 90% by volume, and at least 90 wt % of the monomers are reacted; in a second continuous polymerisation phase, the reactants are continuously supplied to the first polymerisation reactor and product is continuously withdrawn, and the product is continuously transferred into a second polymerisation reactor, and in the second polymerisation reactor the polymerisation is continued until at least 98 wt % of the monomers used have reacted.

    Abstract: Building materials containing copolymers derived from vinyl ester, (meth)acrylic ester and optionally ethylene comonomers, stabilized with a polyvinylalcohol protective colloid, as their aqueous dispersions or as redispersible polymer powders which are redispersible in water, exhibit improved processing properties and set properties. The copolymers are obtained by emulsion or suspension copolymerization in an at least two step process wherein a) the vinyl ester component is polymerized, optionally with ethylene and further copolymerizable comonomers, to a conversion of from 90 to 100% by weight in a first step, and b) the ester(s) of (meth)acrylic acid are subsequently added and polymerized in a second step. The copolymer dispersion obtained may be dried to form a redispersible copolymer powder.
