Application 08/312,493
THE INVENTION
Appellants claim an insulating enameling lacquer for use
in making enameled conductors, comprised of a blend of two
recited polymers and a compatibilizing copolymer. Appellants
also claim a process for making the lacquer, and claim an
enameled wire comprising an external layer of an enamel
obtained by reticulation of the lacquer. Claim 1, which is
directed toward the lacquer composition, is illustrative and
reads as follows:
1. An insulating enameling lacquer for enameled
conductors comprising a polymer blend of a base first polymer,
a second polymer and a copolymer, wherein:
the base first polymer is selected from the group
consisting of:
polyurethane, polyamide, polyamide imide, polyester,
polyester imide, polyester amide-imide, polyamide,
acetal of polyvinyl alcohol, polyepoxy compounds and
polyphenoxy compounds;
the second polymer is selected from the group consisting
of polysiloxanes;
said second polymer is present in the blend in a
quantity of at least 0.3% but less than 30% by weight;
and
