Abstract:
A stabilized resin composition comprising:(a) a thermoplastic resin or mixture thereof, and(b) a stabilizing amount of a compound selected from the group consisting of an aromatic ketone compound having the formula: ##STR21##whereinR.sup.1 and R.sup.2 are each independently a hydrogen, hydroxyl, thio, thio-ether, alkoxy, aryloxy, or alkyl moiety, and each R.sup.3 is independently a hydrogen, alkyl, aryl, or substituted alkyl moiety containing at least one --O--, --S--, --SO--, --CO.sub.2 --, --CO--, or --CON-- moiety, and wherein there may be multiple R.sup.1 and R.sup.2 groups; an aromatic ketone compound having the formula: ##STR22##whereinR.sub.1 and each R.sup.2 is independently a hydrogen, alkyl, aryl, or substituted alkyl or substituted aryl moiety containing at least one --O--, --S--, --SO--, --CO.sub.2 --, --CO--, or --CON-- moiety, and wherein there may be multiple independent R.sup.1 groups; an aromatic ketone compound having the formula: ##STR23##whereineach T can independently be hydrogen, hydroxyl, thio, thio-ether, alkoxy, aryloxy, or alkyl moiety, and R can be hydrogen, alkyl, hydroxy, aryloxy, arylmethoxy, halo, mercapto, amino, substituted mercapto, or substituted amino, and wherein there may be multiple independent R and T groups present, and wherein X is selected from alkylidene and substituted alylkidene, and wherein n ranges from 0 to about 6;a derivative of an aromatic ketone compound having the formula: ##STR24##whereinR.sup.1 and R.sup.2 are independently a hydrogen, hydroxyl, thio, thio-ether, alkoxy, aryloxy, or alkyl moiety, and each R.sup.3 is independently a hydrogen, alkyl, aryl, or substituted alkyl or substituted aryl moiety containing at least one --O--, --S--, --SO--, --CO.sub.2 --, --CO--, or --CON-- moiety, and wherein there may be multiple independent R.sup.1 and R.sup.2 groups, and wherein Z is selected from the group consisting of NR.sup.4, N(OH), NNHR.sup.4, and NOR.sup.4 wherein R.sup.4 is alkyl, aryl or an substituted alkyl or substituted aryl moiety, optionally containing at least one --O--, --S--, --SO--, --CO.sub.2 --, --CO--, or --CON-- moiety;and an adduct of an aromatic ketone compound having the formula: ##STR25##whereinR.sup.1 and R.sup.2 are independently a hydrogen, hydroxyl, thio, thio-ether, alkoxy, aryloxy, or alkyl moiety, and wherein there may be multiple R.sup.1 and R.sup.2 groups, and R.sup.3 is a hydrogen, alkyl, aryl, or substituted alkyl or substituted aryl moiety containing at least one --O--, --S--, --SO--, --CO.sub.2 --, --CO--, or --CON-- moiety and wherein R.sup.4 and R.sup.5 are independently hydrogen, alkyl, aryl, alkaryl, ester, acid, ether, amide, thioester, amine, or interconnected to form a ring, such as an imide or anhydride, and wherein each of R.sup.4 and R.sup.5 may independently contain additional species of the group consisting of hydrogen, alkyl, aryl, alkaryl, acid, ester, hydoxyl, imide, amide, anhydride, thioester, ether, thioether, phosphate, oxazoline, epoxy, amino, and orthoester.
