ABSTRACT:
The invention relates to heterocyclic functional polyurethane polymers and their use in magnetic recording media. The polymer is selected from the group consisting of polyurethane and polyurethane urea wherein the polymer has a heterocyclic group equivalent weight of from about 500 to about 100,000 and wherein the heterocyclic group is derived from compounds selected from the group consisting of ##STR1## tautomers thereof, and mixtures thereof, wherein the heterocyclic group is formed by reacting said heterocyclic compound into said polymer.
