Disclosed are novel blends comprising segmented polyesteramides with minor amounts of carbodiimide containing materials.
The blends are characterized by excellent physical properties and improved compression set characteristics over the polyesteramides in the absence of the carbodiimide component. This allows the polymers obtained to find utility in the making of seals or gaskets which heretofore the base polyesteramides could not satisfy.
