Abstract: The invention concerns highly dispersible powders based on carboxylated butadiene-containing copolymers of styrene and/or acrylonitrile, the films of these powders drawn from the redispersion displaying high tensile strength. According to the invention, the latices are atomized with mixtures of atomizing aids consisting of between 1 and 15 wt % of a salt of alkylated di-phenyl-ether-di-sulphonic acid, caseinate and/or N-alkylsulphosuccinamide and/or with between 1 and 20 wt % of a di- or tetra-sodium or potassium salt of an addition product of N-alkyl-sulphosuccinamates with maleic acid in a mixture with polyvinylalcohol. The dispersions can predominantly be used in the construction industry and are alternatives to the copolymers based on polyvinylacetates and acrylates.

Abstract: Primary polymer particles having a size at least 90 % below 10 mu m and which contain water-soluble and water-insoluble polymer are made by reverse phase polymerisation of a water-soluble ethylenically unsaturated monomer or monomer blend with cross-linking agent, and the emulsion is then spray-dried to form spray-dried granules which disintegrate upon addition to water, thereby forming an aqueous composition of the insoluble particles having activity similar to the starting emulsion. This aqueous composition of insoluble particles is particularly useful for flocculation, for instance, flocculation of sewage sludge followed by centrifugation or belt pressing, or for viscosification.

Abstract: The invention relates to a process for the preparation of powder compositions, containing organosilicon compounds and redispersible in water, by spray drying of an aqueous mixture containing one or a plurality of organosilicon compounds and one or a plurality of water-soluble organopolymers in the presence of antiblocking agents. The invention is characterised in that a portion of the antiblocking agent is fed at the same time as the aqueous mixture but separately therefrom into the upper section of the dryer and the remainder of the antiblocking agent is conveyed to the dried powder stream, as long as it is still suspended in the stream of gas, or the remainder of the antiblocking agent is added to the dried powder.

Abstract: A process for producing a polytetrafluoroethylene (hereinafter abbreviated to "PTFE") molding powder comprising fine grinding of coarse PTFE particles in a wet state, which permits washing of PTFE in a finely ground state and efficient reduction in the impurity content of PTFE, and another process therefor by agglomerating and granulating the above finely ground and washed PTFE particles, which permits the production of a PTFE powder in less process steps. The former process is characterized in that coarse PTFE particles prepared by suspension polymerization of tetrafluoroethylene are finely ground in a wet state to form fine particles particularly having a mean particle diameter of 10 to 100 mu m and and thereafter the resulting fine particles are washed, while the latter process is characterized in that the washed fine PTFE particles are agglomerated and granulated in a wet state by application of a mechanical force to form particles having a mean particle diameter of 200 to 800 mu m.
