摘要:
The invention relates to a method for the production of protective colloid-stabilized polymer products by means of emulsion polymerization in a reactor having an external cooling circuit, which is equipped with a pump and a heat exchanger, characterized in that the reaction mixture present in the reactor is delivered to a cooled static mixer-heat exchanger having stationary fixtures and is subsequently returned to the reactor. The invention further relates to a device for the production of protective colloid-stabilized polymer products by means of emulsion polymerization, comprising a reactor and an external cooling circuit, characterized in that the external cooling circuit is equipped with a pump and a cooled static mixer-heat exchanger having stationary fixtures.
摘要:
The invention relates to a method for applying dispersion adhesives containing one or more polyvinyl esters and optionally one or more additives, characterized in that one or more polyvinyl esters are produced by radical-initiated, continuous emulsion polymerization of a) one or more vinyl esters and, optionally, b) one or more additional ethylenically unsaturated monomers, and the dispersion adhesives are applied to a substrate by way of mechanical application methods.

The present invention relates to methods for producing protective-colloid-stabilized aqueous dispersions of vinyl ester polymers having weight-average particle diameters Dw of 120 nm to 1,500 nm and a polydispersity PD
摘要:
The invention provides paper coating slips comprising, as a binder, an aqueous dispersion of a styrene-butadiene copolymer or of a styrene-acrylic ester copolymer, or a mixture of these aqueous dispersions, characterized in that an aqueous dispersion of a polyvinyl alcohol-stabilized vinyl acetate-ethylene copolymer is additionally present in each case.
