One-pot 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 vessel, dimethylacetamide solvent, an inorganic azide, and a divalent zinc salt with a nitrile having the general structure (II),
• where “n” of said nitrile has a value of 2 to 9 and “X” is a group consisting of at least one of alkyl, aryl, and oligoether, 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, to form a first composition including the poly tetrazole having the general structure (III), wherein “n” has a value of 2 to 9, and “H” is chemically bonded to N1 or N2
• adding 2-chloroethanol and an inorganic base to said vessel to form a second composition;
• incubating said second composition 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 24 hours, allowing contact of reactants in said vessel, to form a third composition;
• distilling said third composition at about 100° C. under low pressure to remove said dimethylacetamide from said vessel to form a fourth composition;
• adding acetone to said fourth composition in said vessel to form a fifth composition including a precipitate;
• distilling said fifth composition under low pressure to remove said acetone from said vessel to form a sixth composition including the tetrazole polyol having the general structure (I), where “n” of said polyol has a value of 2 to 9, and “R” is a group consisting of at least one of alkyl, aryl, and oligoether, that is chemically bonded to N1 or N2.

• where “n” of said nitrile has a value of 3 and “X” is propane, 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, to form a first composition including the poly tetrazole having the general structure (III), wherein “n” has a value of 3, and “H” is chemically bonded to N1 or N2
