THE CORROSIVE EFFECTS OF HALOGEN-CONTAINING POLYMER VULCANIZATES CAN BE INHIBITED BY THE ADDITION OF A SMALL AMOUNT OF THE MIXTURE OF (1) AT LEAST ONE CORROSION INHIBITING AGENT HAVING THE GENERAL FORMULA (R)N-A-(COOM)M WHERE EACH R INDEPENDENTLY IS SELECTED FROM ALKYL, ARYL, CYCLOALKYL, ALKOXY, HYDROXY, HALO, NITRO, AMINO, THIO, AND ESTER RADICALS; A IS SELECTED FROM THE GROUP OF POLYVALENT AROMATIC RADICALS DERIVED BY THE REMOVAL OF A NUMBER OF HYDROGEN ATOMS EQUAL TO THE SUM OF N PLUS M FROM PHENYL, NAPHTHYL, BENZOPHENONE, BIPHENYL, ALKYLPHENYL AND ALKENYLPHENYL RADICALS; M IS SELECTED FROM H, NHXR''Y WHERE R'' IS LOWER ALKYL, X IS AN INTEGER FROM 2 TO 4, Y IS AN INTEGER FROM 0 TO 2 AND X+Y=4, AND METALS SELECTED FROM GROUPS II-A, II-B, IV-A AND VIII OF THE PERIODIC CHART OF ELEMENTS; N IS AN INTEGER FROM 0 TO 3; AND M IS AN INTEGER FROM 1 TO 2; AND (2) AT LEAST ONE LEAD COMPOUND SELECTTED FROM THE LEAD SALTS OF ALIPHATIC CARBOXYLIC ACIDS, LEAD SALTS OF AROMATIC CARBOXYLIC ACIDS, LEAD SALTS OF CARBONIC ACID, LEAD SALTS OF PHOSPHOROUS ACID, LEAD SALTS OF SILICIC ACID AND LEAD OXIDES. |
