摘要：Molding compositions MC having a reduced tendency to yellow with thermalstress which consist of a polymer PM containing units of formula I: ##STR1## blendingfrom 0.005-1 wt % of at least one reducing inorganic phosphorus compound IP selectedfrom the group consisting of phosphinic and phosphonic acid and its alkali metal,

alkaline-earth metal, a aluminum and ammonium salts, wherein the ammonium ion can besubstituted with up to four C.sub.1 -C.sub.4 alkyl and/or C.sub.5 -C.sub. 8 cycloalkylgroups, with the polymer PM after conclusion of the imidation reaction.
