Flame retardant additive of fluoropolymers in flame retardants

Abstract

The problem of lack of uniform dispersion of a fluoropolymer as a flame retardant additive to thermoplastic resins is solved by a dispersion of a fluoropolymer in a flame retardant which is then blended as particles with a thermoplastic resin in molten form. Furthermore, flame retardant precursors are reacted in the presence of a fluoropolymer to form a molten flame retardant mixed with the fluoropolymer in another aspect.

         14 . Process for making a composition having one or more fluoropolymers dispersed in one or more flame retardants, comprising:
 (i) melting the flame retardant;   (ii) mixing the fluoropolymer with said molten flame retardant;   (iii) allowing the mixture to solidify; and   (iv) particulating the solidified mixture.   
     
     
         15 . Process for making a composition having one or more fluoropolymers dispersed in one or more flame retardants, which comprises
 providing flame retardant precursors in molten condition,   mixing said precursors with the fluoropolymer and optionally with a catalyst,   reacting said precursors to form a molten flame retardant mixed with said fluoropolymer,   allowing the mixture to solidify and particulating the solidified mixture.
