    摘要: The present invention relates to a continuous process for the production of impact resistance-modified thermoplastics. An elastomer, in particular a particulate graft polymer with a water moisture content of 1 to 50%, preferably 10 to 40%, is incorporated into a thermoplastics melt in a large volume kneader reactor. The mixing ratio of elastomer to thermoplastics melt is 4:1 to 1:4. The energy required to melt the elastomer and to evaporate the adhering water is added by heating the walls of the apparatus and via the kneading action of the installed rotating parts.

    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.
