MOULDINGS WITH A UNIFORM PARTICLE SIZE AND THERMAL STABILITY

摘要

1. A process for the production of elastic-thermoplastic and thermoplastic powder-form moulding compounds, characterized in that the moulding compounds are mixed in the form of their latices with from 0.75 to 10 parts by weight (based on 100 parts by weight of latex solids) of a sulfur-containing, elastic-thermoplastic graft product present in emulsion form, of which the thermoplastic component of the monomers polymerized onto the rubber has a Vicat A/120-softening temperature according to DIN 53 460 of from 30 degrees C to 95 degrees C, a rubber content of 1 to 80% by weight and a gel content of 5 to 95% by weight (as measured in acetone at 25 degrees C) and in which has a sulfur content introduced by incorporated, optionally substituted thioalkyl groups of from 0.5 to 5.0% by weight and are precipitated by the addition of a coagulant at temperatures of from 75 to 120 degrees C, optionally under pressure, followed by working up.
