Abstract:
1. A process for preparation of a polymer of structure (VII) comprising: reacting an isocyanate resin with an effective amount of tetrazole diol of structure (II), wherein “X” is an alkyl, aryl, or oligoether group, wherein “R” is an alkyl, aryl, or oligoether group, wherein “R” is chemically bonded to N 1 or N 2 , at a temperature from about 50° C. to about 100° C. from about 1 hour to about 48 hours; wherein said isocyanate resin is of structure (VIII), wherein “Y” is an alkyl, aryl, or oligoether group, wherein “m” is 2-9, cooling to room temperature; and, extracting a linear polyisocyanate polymer of structure (VII) wherein “X” is an alkyl, aryl, or oligoether group, wherein “Y” is an alkyl, aryl, or oligoether group, wherein “m” is 2 to 9, wherein “p” is 5 to 10,000, wherein “R” is an alkyl, aryl, or oligoether group, wherein “R” is chemically bonded to N
