Abstract
A compatibilizer including a first portion compatible with a fluoropolymer and a second portion compatible with a polyolefin. Compatibilized compositions comprising a polyolefin, a fluoropolymer, and a compatibilizer are also disclosed. Methods for forming both the compatibilizer and the blends contained in the compatibilizer are described. The compatibilized compositions of the present invention exhibit desired mechanical properties such as tensile strength and elongation. The flame retarded compatibilized blends exhibit desirable dielectric properties, are flame resistant and exhibit low smoke emission.

A compatibilizer for blends including a fluoro(co)polymer and a polyolefin, comprising the reaction product of:
- a) a fluoro(co)polymer having a functional group and a polyolefin polymer or copolymer having a functional group, said functional groups being complementary and reactive with each other;
- or
- b) a fluoro(co)polymer having a functional group, a polyolefin polymer or copolymer having a functional group, said functional groups being the same or non-reactive with each other, and a bridging compound having at least two functional groups with said bridging compound first functional group reactive with said fluoro(co)polymer functional group and said bridging compound second functional group reactive with said polyolefin functional group.
A compatibilizer for blends including a fluoro(co)polymer and a polyolefin, comprising the reaction product of:
- a) a fluoro(co)polymer having a first functional group, wherein the first functional group is an unsaturated hydrocarbon group, an amino group, a hydroxyl group, a carboxylic acid group, an anhydride group, an epoxy group or an isocyanate group;
- and
- b) a polyolefin polymer or copolymer having a second functional group, wherein the second functional group is an unsaturated hydrocarbon group, an amino group, a hydroxyl group, a carboxylic acid group, an anhydride group, an epoxy group or an isocyanate group, wherein the first functional group is different from and reactive with the second functional group.
A compatibilizer, comprising the reaction product of:
- a) a fluoro(co)polymer having a functional group and a polyolefin polymer or copolymer having a functional group, said functional groups being complementary and reactive with each other;
- or
- b) a fluoro(co)polymer having a functional group, a polyolefin polymer or copolymer having a functional group, said functional groups being the same or non-reactive with each other, and a bridging compound having at least two functional groups with said bridging compound first functional group reactive with said fluoro(co)polymer functional group and said bridging compound second functional group reactive with said polyolefin functional group,
- wherein the fluoro(co)polymer functional group is an unsaturated hydrocarbon group, an amino group, a hydroxyl group, a carboxylic acid group, and anhydride group, an epoxy group or an isocyanate group, and wherein the polyolefin functional group is an unsaturated hydrocarbon group, an amino group, a hydroxyl group, a carboxylic acid group, an anhydride group, an epoxy group or an isocyanate group.
A compatibilizer, comprising the reaction product of:
- a) a functional group containing fluoro(co)polymer derived from the reaction product of a fluoro(co)polymer having at least one labile hydrogen atom bonded to at least a main chain carbon atom and a first linking compound having at least two functional groups with the first linking compound first functional group reactive with the fluoro(co)polymer;
- and
- b) a functional group containing polyolefin(co)polymer derived from a polymerization reaction comprising at least two olefin monomers and a second linking compound group having a polymerizable functional group and a second functional group, wherein the first linking compound second functional group and second linking compound second functional group are different and reactive with each other.
