Abstract

A cross-linked polyisocyanate polymer and a process for preparation of a polymer having the general structure (I) including reacting an effective amount of tetrazole polyol with isocyanate resin, combining at a temperature in the range of about 50° C. to about 100° C. for a time period in the range of about 1 to about 24 hours and cooling to room temperature producing a cross-linked polyisocyanate polymer.
