         2 . The composition of  claim 1 , wherein the composition is selected from at least one of CH 3 C 2 H 3 NC(O)NHC 6 H 7 (CH 3 ) 3 CH 2 HNCOOCH 2 C≡CH, CH 3 C 2 H 3 NC(O)NHC 6 H 7 (CH 3 ) 3 CH 2 HNCOOCH 2 CH 2 N 3 , OCNC 6 H 7 (CH 3 ) 3 CH 2 NHCOOCH 2 C≡CH, and OCNC 6 H 7 (CH 3 ) 3 CH 2 NHCOOCH 2 CH 2 N 3 . 
     
     
         3 . A mixture comprising:
 (a) a non-self-crosslinking polymer; and   (b) the composition of  claim 1 .   
     
     
         4 . The mixture of  claim 3 , wherein the non-self-crosslinking polymer comprises a reaction site selected from at least one of a hydroxyl, an amino, a carboxy, an epoxy, a double bond, a ketone, an aldehyde, or non-self-reactive combinations thereof. 
     
     
         5 . The mixture of  claim 3 , wherein the non-self-crosslinking polymer is selected from at least one of: (meth)acrylates, polyurethanes, polyesters, polysiloxanes, polyolefins, polyethers, polyamides, or combinations thereof.

         7 . The mixture of  claim 6 , wherein the curing agent is a small molecule. 
     
     
         8 . The mixture of  claim 6 , wherein the curing agent is a second polymer. 
     
     
         9 . The mixture of  claim 8 , wherein the second polymer is different than the non self-crosslinking polymer.
