Process for making multifunctional tetrazole polyols to produce tetrazole based polymers

A process for preparation of a compound of structure (I) comprising:

• wherein “n” is 2-9 and “X” is a group consisting of at least one of alkyl, aryl, and oligoether,
• reacting in a first solvent an inorganic azide and a divalent zinc salt with a nitrile having the general structure (II), where “n” of said nitrile is 2 to 9, at a temperature in the range from about 70° C. to about 170° C. for a time period in the range from about 1 hour to about 24 hours, allowing contact of reactants, wherein “X” is a group consisting of at least one of alkyl, aryl, and oligoether, to form a first composition;
• cooling said first composition to about room temperature to form a second composition including poly tetrazole having the general structure (III), wherein “n” is 2 to 9, and “H” is chemically bonded to N1 or N2;
• isolating said poly tetrazole by precipitation from a suitable second solvent;
• reacting said poly tetrazole in a third solvent with a soluble reversible or non-reversible base and 2-chloro-ethanol at a temperature in the range from about 70° C. to about 150° C. for a time period in the range from about 1 hour to about 10 hours, allowing contact of reactants, to form a third composition;
• cooling said third composition to about room temperature to form a fourth composition including tetrazole polyol having the general structure (I), wherein “R” is a group consisting of at least one of alkyl, aryl, and oligoether, and “R” is chemically bonded to N1 or N2 of said tetrazole polyol.
