Abstract

PURPOSE: Title composition with improved heat stability, that is composed of a thermoplastic resin and a chroman derivative.
CONSTITUTION: Said composition comprises 100 parts by wt of a thermoplastic polymer from ethylenically unsaturated monomers such as a polymer from an α- olefin of 10 or less carbon atoms and 0.005W0.5, preferably 0.01W0.2 parts of a chroman derivative of formula I (R1 is hydrocarbyl of 1-16 carbon atoms; R2W7, R9, R10 are H, alkyl of 1-7 carbon atoms; R8 is group containing O, S, P and/or N). The chroman derivative is, e.g., preferably the one having residue of phosphorus oxo acid shown as formula II or III (n is 1W3; R11, R13 are H, alkyl; R12, R14 are H, alkyl, group of formula IV) as R8 in formula I. The combined use of phosphoric acid, organic oxyacids or imidazole shows synergistic effect
