THERMOPLASTIC MOLDING MASSES AS WELL AS A PROCEDURE FOR THE REDUCTION OF THE RESIDUAL MONOMER FORMATION IN THESE MOLDING MASSES.

摘要

THE INVENTION REFERS TO THERMOPLASTIC MOLDING MASSES, WHICH CONTAIN A) BETWEEN 98.99 AND 99.995% IN REFERENCE WEIGHT AA + B, OF AT LEAST ONE POLYMER CONTAINING ACRYLONITRILE AND B) BETWEEN 0.005 AND 2% IN WEIGHT, REFERENCE AA + B DE AL} - TOCOFEROL. FURTHER, THE INVENTION REFERS TO A PROCEDURE FOR THE REDUCTION OF THE FORMATION OF RESIDUAL MONOMERS WHEN THE MOLDING MASSES ARE SUBJECT TO THERMAL AND SHEAR VOLTAGES THROUGH THE ADDITION OF AL} - TOCOFEROL.
