    摘要: A process for the continuous processing of vinyl polymer latices to produce thermoplastically processible vinyl polymer powder by coagulating a stream of a vinyl polymer latex by the addition of a stream of a coagulant with intensive mixing and shearing in a cascade of vessels at an average residence time per vessel of 10 to 60 minutes and at temperatures from 50 to 120.degree. C., volatile auxiliary substances and residual monomers in the polymer being optionally removed by steam distillation and part of the serum separated from the vinyl polymer being added to the stream of coagulant.

    摘要: A process for the production of pourable, free-flowing granules which are suitable for use as wetting agents, detergents or cleaning products from aqueous solutions or suspensions of such materials in a fluidized-bed spray granulation apparatus employing a hot fluidizing gas. The aqueous selections or suspensions are dried with superheated steam as the fluidizing and drying gas wherein the drying step is carried out in a closed-loop system comprising a steam circuit from which the water evaporated from the aqueous solutions or suspensions of starting materials is removed as a partial stream and the thermal energy released is returned to the steam circuit. The granules are discharged from the granulation apparatus before they can be damaged by heat.

    摘要: An .alpha.-methylstyrene/acrylonitrile copolymer obtainable by emulsion polymerization which, in combination with other polymers, particularly PVC, enables alloys of outstanding thermal stability and color stability to be produced and, in addition, has a high heat distortion temperature and shows good fogging behavior and which is obtained by radically initiated inflow copolymerization of a mixture of 30 to 32 parts by weight acrylonitrile and 68 to 70 parts by weight .alpha.-methylstyrene in the presence of an emulsifier containing carboxyl groups. The polymerization is conducted in such a way that a seed latex of the same copolymer or of an analogous copolymer is introduced before addition of the monomers is commenced, the reaction temperature is kept between 75.degree. and 82.degree. C. and the molar ratio of emulsifier to initiator is between 4 and 6.

    摘要: This invention relates to a granular, free-flowing detergent component which dissolves rapidly in water and which has a powder density of from 550 to 900 g/l, consisting of synthetic, essentially nonionic surfactants, inorganic supports, other organic washing aids, and water bound by adsorption and in hydrate form. The detergent component is produced by spray-drying, and more than 50% by weight thereof consists of droplet-like to rodlet-like particles having an average diameter of from about 0.02 to 1.5 mm, an average length of from about 0.1 to 5 mm, and a ratio of average diameter to average length of from about 1:1.2 to 1:10, optionally coated with a finely divided water-soluble or water-dispersible solid material as a fluidity improving agent.
