    Abstract: PROBLEM TO BE SOLVED: To provide an enamel having a low coefficient of friction stably for a long time without a residue remaining in a polymerization oven. SOLUTION: The method for producing the enamel selected from polyamides, polyamide-imides, polyesters, polyester-imides, etc., reacting a functionalized polysiloxane having a reactive first functional group with a first functionalized monomer used in synthesizing the enamel and having a second functionalized group reactive with the first functional group, providing a functionalized polysiloxane oligomer and subsequently comprising the following steps. The functionalized siloxane oligomer is reacted with a second functionalized monomer used in synthesizing the enamel and the second monomer has a third functional group reactive with the functionalized polysiloxane oligomer. Thereby, a graft-polymerized polysiloxane having organic chains identical to those of the enamel is obtained. The enamel is synthesized by using the first and second monomers and the graft-polymerized polysiloxane. COPYRIGHT: (C)2004,JPO

    Abstract: PROBLEM TO BE SOLVED: To obtain a varnish that is a hybrid and a composite capable of manufacturing winding wires unexpectedly presenting an ability to withstand partial discharge that is greatly increased as compared with wires coated with a varnish of prior art, particularly at high temperatures. SOLUTION: This varnish composition is a varnish for the winding wires containing a copolymer obtained from a thermoplastic or a thermosetting resin and containing units derived from a silane and a mineral filler selected from the compounds of B, Al, Ti, Zn, Zr, Cr, Fe, a silicate and a mixture thereof. The resin is selected from among a polyamideimide(PAI), a polyesterimide(PE), a polyimide(PI), a polyester(PE), a polyurethane(PU) and a polyvinyl acetal(PVA). The varnish makes it possible to obtain the winding wires of lifetime that is increased by having an improved ability to withstand the partial discharge and voltage peak even at high temperatures. The varnish composition is applicable to the manufacturing of coils, in particular for variable frequency controllers and converters.
