    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： A phosphate-reduced, granular free-flowing detergent containing (a) from 5 to 40% nonionic surfactant, (b) from 3 to 20% anionic surfactant, (c) from 15 to 50% zeolite, (d) from 0.5 to 15% homopolymeric or copolymeric carboxylic acid or alkali metal salts thereof and (e) from 10 to 72.5% detergent constituents which are stable under spray-drying conditions, with the proviso that the detergent comprises a mixture of two powder components (A) and (B) in a weight ratio of from 1:5 to 3:1, component (A) containing from 50 to 100% of constituent (a), from 80 to 100% of constituent (c) and from 50 to 100% of constituent (d). Component (A) has an average particle size of from 0.4 to 0.8 mm and a powder density of from 500 to 800 g/l. Component (B) contains from 80 to 100% of constituent (b) and 100% of constituent (e), has a powder density of from 300 to 500 g/l and differs in its particle size distribution by at most 50% from the particle size distribution of component (A).
