  • Use of organocopper complexes with amine molybdates as smoke suppressants in halogen containing polymeric compositions
    Patent number: 6355277
    Abstract: There is disclosed a method of improving the smoke suppressant characteristics of halogen-containing polymeric compositions which comprises adding to said polymeric compositions a smoke retardant amount of (1) a complex of a cuprous halide and a phosphite, and (2) an amine molybdate which contains no residual molybdenum trioxide prepared by reacting an amine with molybdenum trioxide in an aqueous acidic medium under greater than atmospheric pressure and at a temperature of from 105-150° C.
    Type: Grant
