Method of manufacturing an enamel having a low coefficient of friction, and an electrical conductor coated in such an enamel

A method of manufacturing an enamel selected from:

• polyurethanes, polyamides, polyamide-imides, polyesters, polyester-imides, polyester amide-imides, polyimides, polyepoxy compounds, and polyphenyl oxide compounds;
• said method comprising the step of:
• synthesizing an enamel by polymerizing a first monomer, a second monomer and a grafted polysiloxane macromonomer, said grafted polysiloxane having an organic segment identical to those of the organic polymer backbone of the enamel;
• wherein said grafted polysiloxane is formed by (i) reacting a polysiloxane bearing a functional group with an excess of a first monomer, having a first functional group that reacts with the functional group bonded to said polysiloxane and a second functional group that reacts with a functional group of the second monomer and (ii) oligomerizing the second monomer with the product mixture of step (i), thereby providing a grafted polysiloxane macromonomer with the proviso that the first and second monomers used in the macromonomer forming step are the same as the first and second monomers used in the enamel synthesis step such that the organic segment of the polysiloxane macromonomer is identical to the backbone of the enamel.
