Abstract
Abstract Polyesteramides modified by having at least one terminal norbornene radical have improved physical and chemical properties, such as enhanced corrosion resistance, electrical properties, and heat stability. The modified polyesteramides are prepared by a process of reacting a dicarboxylic acid, a diamine, a polyol and a norbornene compound.
