Abstract

A method of forming a resin powder of a sterile polymer suitable for deposition on an electrical conductor, comprising preparing a polyester by reacting at least one polyvalent alcohol and at least one carboxylic acid selected from the group consisting of polycarboxylic acids and derivatives of polycarboxylic acids, in the presence of a difunctional organic tin compound, to produce a hydroxy-terminated polyester with tin atoms in the fundamental structure of the polymer, form a polyimide by reacting a diamine and an aromatic carboxylic anhydride containing at least an additional carboxylic group, prepare an esterimidic polymer by reacting said polyimide with said hydroxy-terminated polyester containing tin, to obtain a thermostable, branched, esterified ester-containing resin in the fundamental structure of the polymer, and grinding said resin is branched termini up to a particle size between approximately 10 and 150 micrometers, for powder deposition on a conductor.
