Process for preparing an enamel coating having a low friction index and an enamel-coated electrical conductor

摘要

Production of an enameling lacquer (I) of polyurethane, polyamide, polyamide-imide, polyester, polyester-imide, polyester-amide, polyimide, polyepoxide or polyphenoxide comprises: (a) reacting a functionalized oligomeric polysiloxane with a second functionalized monomer to give a grafted polysiloxane containing the organic chains of (I); and (b) synthesizing (I). Production of an enameling lacquer (I) of polyurethane, polyamide, polyamide-imide, polyester, polyester-imide, polyester-amide, polyimide, polyepoxide or polyphenoxide, including reaction of a functionalized polysiloxane (II) containing a first functional group (FG1) with a first functionalized monomer (FM1) containing a second functional group (FG2) reactive with FG1, comprises: (a) reacting the obtained functionalized oligomeric polysiloxane (III) with a second functionalized monomer (FM2) containing a third functional group (FG3) reactive with (III), to give a grafted polysiloxane (IV) containing the organic chains of (I); and (b) synthesizing (I) from FM1, FM2 and (IV).
