Thermoplastic molding compounds and a method of reducing the formation
of residual monomers in these molding compounds
摘要:
The invention relates to thermoplastic molding compositions consisting ofA) 98-99.995% by weight, based on A+B, of at least one acrylonitrile-containing polymer, andB) 0.005-2% by weight, based on A+B, of .alpha.-tocopherol.The invention also relates to a method for reducing the formation of residual monomers on thermal stress and shearing of the thermoplastic molding compositions by adding .alpha.-tocopherol.
