  • Patent number: 7655726
    Abstract: The present invention relates to novel molding compositions based on semicrystalline engineering thermoplastics which, in conventional processing techniques, give moldings with reduced surface gloss. A feature of the molding compositions is that they comprise, in a polymer matrix, if appropriate with the usual additives, polymer particles with a median size d50 of from 0.1 ?m to 100 ?m, and comprise at least one other incompatible or semicompatible polymer which has not been chemically crosslinked, and also, if appropriate, comprise salt-like additives. The invention further relates to moldings which are produced by means of conventional processing techniques, in particular via injection molding, from these matt-effect molding compositions.

  • Patent number: 7485680
    Abstract: A process for efficiently producing an agglomerate resulting from removal of impurities from a water-base latex of rubbery polymer particles or dry Powder thereof and producing a dispersion having rubbery polymer particles dispersed in an organic solvent, and a process for efficiently producing a resin composition of low impurity content, in which the state of dispersion of rubbery polymer particles is excellent, from the above dispersion. In particular, a rubbery polymer particle agglomerate of low impurity content is obtained by first mixing a water-base latex of rubbery polymer particles with an organic solvent exhibiting partial solubility in water, bringing the resultant mixture into contact with water to thereby form a rubbery polymer particle agglomerate, and thereafter separating the water phase from the agglomerate/water phase mixture.
