Title: Elzbieta Wardzinska: Innovator in Wire Enamels and Varnishes
Introduction
Elzbieta Wardzinska is a notable inventor based in Grodzisk Mazowiecki, Poland. She has made significant contributions to the field of electrical insulation through her innovative patents. With a total of 2 patents, her work focuses on enhancing the properties of wire enamels and varnishes.
Latest Patents
One of her latest patents is for "Cresol-free or low-cresol wire enamels." This invention relates to wire enamels based on polyester, polyesterimide, polyesteramidoimide, and/or polyurethane resins. These enamels contain one or more of these resins as binders, along with organic solvents and optional diluents. Notably, at least 50% by weight of the solvent or solvent/diluent mixture consists of a monocyclic aromatic alkyl-carboxylic acid ester or isophorone, or a mixture of methyl benzoate and isophorone.
Another significant patent is for a "Method for making polyesterimide varnishes." This method involves polycondensing and imidating a mixture of trimellitic anhydride, 4,4'-diamino-diphenyl methane, glycol, dimethyl terephthalate, and glycerol or tris(hydroxyethyl) isocyanurate. A transesterification catalyst is added, and the resulting polyesterimide resin is dissolved in an organic solvent with a crosslinking catalyst. The method is characterized by the use of 2-methyl-1,3-propanediol and/or 2-butyl-2-ethyl-1,3-propanediol as the glycol or one of the glycols.
