Claim 15:
16. A process of producing an alternative polyurethane composition, the process comprising reacting an azidated polyol and a poly(alkynyl carbamate) prepolymer at a temperature of from 20° C. to 200° C., optionally in the presence of a catalyst, wherein the poly(alkynyl carbamate) prepolymer comprises a reaction product of stoichiometric equivalents of a polyisocyanate component and a hydroxyl-functional component, wherein the hydroxyl-functional component comprises 1-100% by weight of an alkynol-ether of the formula (I),

HC≡C—R—OH  (I),

wherein R is a linear or branched ether chain having from 1 to 15 atoms, and wherein the remainder of the hydroxyl functional component comprises an alkynol.
