    摘要: A process for refinishing the surface of a body of acrylo-butadiene-styrene (ABS) polymer by applying to the surface a coating material and treating the body with a solvent. The surface is cooled, together with at least the material underlying the surface, to a temperature in the range about 32.degree. F. to 40.degree. F. The surface of the body is then contacted with a solvent vapor for a time sufficient to reflow the surface but not to warm appreciably the inner layer of the body. The process avoids distortion in the refinished surface.

    摘要: The present invention relates to a process for the production of impact-modified filled polycarbonate compositions and molding compositions. A process of the present invention involves: (i) mixing the CNT (component C) with rubber-containing vinyl copolymer (component B) and/or rubber-free vinyl copolymer (component D) on a twin screw extruder, to obtain a CNT masterbatch, (ii) mixing the CNT masterbatch with polycarbonate (component A) and optionally with Component B and/or Component D and optionally with an additive on a twin screw extruder. A polycarbonate composition prepared according to the present invention does not experience degradation of the molecular weight of the polycarbonate during compounding a compared to processes known in the art.

    摘要: The present invention relates to the use, in a compounding process for the preparation of pigmented impact-modified thermoplastic polymer compositions, of a mixture comprising A) from 60 to 98 parts by weight, based on the sum of components A and B, of at least one graft polymer, used in powder form, consisting of a rubber-elastic core and a grafted polymer component as the shell, B) from 2 to 40 parts by weight, based on the sum of components A and B, of at least one inorganic or organic liquid compound, and C) at least one pigment, characterised in that the graft polymer A and/or the pigment C absorbs or adsorbs the liquid inorganic or organic compound B, and the boiling point of component B at normal pressure is below the temperature of the polymer melt during the compounding.
