Zusammenfassung:	PCT No. PCT/EP96/02896 Sec. 371 Date May 12, 1998 Sec. 102(e) Date May 12, 1998 PCT Filed Jul. 2, 1996 PCT Pub. No. WO97/02314 PCT Pub. Date Jan. 23, 1997The invention relates to thermoplastic molding compositions consisting of A) 98-99.995% by weight, based on A+B, of at least one acrylonitrile-containing polymer, and B) 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.
