Patent ID: 7446208

Claim:
A process for preparation of a polymer of structure (I) comprising: wherein “X” is a group consisting of at least one of alkyl, aryl, and oligoether, wherein “Y” is a group consisting of at least one of alkyl, aryl, and oligoether, wherein “p” is about 5 to about 10,000, wherein “R” is at least one group of alkyls, aryls, and oligoethers, and wherein “R” is chemically bonded to N 1 or N 2 position; reacting an isocyanate resin with an effective amount of a tetrazole diol of structure (II), at a temperature in the range from about 50° C. to about 100° C. for a time period in the range from about 1 hour to about 48 hours, wherein “X” is a group consisting of at least one of alkyl, aryl, and oligoether, wherein “R” is a group consisting of at least one of alkyl, aryl, and oligoether, wherein “R” is chemically bonded to N 1 or N 2 position; said isocyanate resin of structure (III), OCN—Y—NCO (III), wherein “Y” is a group consisting of at least one of alkyl, aryl, and oligoether; cooling to room temperature; extracting a linear polyisocyanate polymer of structure (I).
