Organic materials stabilized by compounds containing both amine and hindered phenol functional functionalities

A stabilizer for organic materials comprising a compound of the general formula:

• ##STR8## R.sub.1 and R.sub.2 are independently selected from the group consisting of hydrogen, unsubstituted aryl, tolyl, xylyl, anilinyl, and alkyl, functionalized alkyl, or aralkyl of 1 to 20 carbon atoms;
• R.sub.3 is alkylene of 1 to 10 carbon atoms;
• m is 0 or 1;
• n is an integer of 1 to 10;
• q is an integer of 0 to 8;
• z is 1 or 2, provided that, when q is 0, z must be 1;
• X represents the links of a chain q links in length, said links being selected from the group consisting of carbon, nitrogen, oxygen, sulfur, silicon, and mixtures thereof;
• and
• Y is an aromatic group or .PHI., provided that Y can be .PHI. only when q is 0 and m is 1 and can be phenyl or alkyl substituted phenyl only when at least one of m and q is not 0.

A method for stabilizing organic materials comprising adding to said materials at least one stabilizer comprising a compound of the general formula:

• ##STR9## R.sub.1 and R.sub.2 are independently selected from the group consisting of hydrogen, unsubstituted aryl, tolyl, xylyl, anilinyl, and alkyl, functionalized alkyl, or aralkyl of 1 to 20 carbon atoms;
• R.sub.3 is alkylene of 1 to 10 carbon atoms;
• m is 0 or 1;
• n is an integer of 1 to 10;
• q is an integer of 0 to 8;
• z is 1 or 2, provided that, when q is 0, z must be 1;
• X represents the links of a chain q links in length, said links being selected from the group consisting of carbon, nitrogen, oxygen, sulfur, silicon, and mixtures thereof;
• and
• Y is an aromatic group or .PHI., provided that Y can be .PHI. only when q is 0 and m is 1 and can be phenyl or alkyl substituted phenyl only when at least one of m and q is not 0.
