Copolymerizates of methyl methacrylate and butyl methacrylate are used as plastisols in the automotive sector and as floor coverings. The invention describes a way to increase the storage stability of the plastisols by using small amounts of cross-linking agents.

Plastisols with cross-linking agents

The present invention is directed to a copolymer containing a hydrophilic copolymerizable monomer and a plastisol obtained by the use of the copolymer, which exhibits reduced viscosity and longer pot-life.

Polyalkyl methacrylate plastisols with improved flow properties

An aqueous synthetic resin dispersion having a minimum film forming temperature below 50.degree. C., containing an emulsion polymer having a core/shell structure consisting of

Aqueous synthetic resin dispersion

A method for obtaining redispersible powders of a copolymer having a dynamic glass transition temperature, T.sub.max, below 150.degree. C., by spray drying an aqueous dispersion thereof having a minimum film forming temperature, MFT, using an inlet temperature T.sub.i and an outlet temperature T.sub.o such that MFT&lt;T.sub.i &lt;T.sub.max and MFT&lt;T.sub.o &lt;65.degree. C.

Method for making redispersible synthetic resin powders

A process for the continuous preparation of aqueous plastic dispersions which comprises emulsifying one or more free-radically polymerizable monomers in an aqueous phase in the presence of an emulsifying agent, in an agitator vessel; initiating the free-radical polymerization of said monomer or monomers in said aqueous phase; and passing said aqueous emulsion of the free-radically polymerizing monomer or monomers through a tubular reactor whose internal surface comprises an (optionally fluorinated)saturated polyolefin.

Continuous emulsion polymerization process

A two-step emulsion polymerization method for making an aqueous emulsion of core/shell polymer particles recoverable as a polymer powder by spray drying the emulsion, said polymer being capable of swelling and forming a gel in gasoline, and paints and coating compositions containing gasoline and such a polymer powder as a thickening agent or binder.
