Abstract
This invention relates to unique and novel polymer complexes between a metal neutralized sulfonated polymer and a tertiary amine terminated polylactone composition. The resulting polymer complexes have a variety of uses including those as diverse as adhesive agents, thermoplastic elastomers, additive uses wherein these materials can be utilized to compatibilize two different polymers which are normally incompatible. These polymer complexes can also be blended with fillers and/or oils when the sulfonated polymer is elastomeric. The materials display thermoplastic character.
