         14 - 15 : (canceled) 
     
     
         16 : The method according to  claim 1 , wherein the 1,1-disubstituted alkene composition exhibits a shelf life of about 3 months or greater when the storage container is maintained at a temperature of about 50° C. and a relative humidity of about 75%. 
     
     
         17 : The method according to  claim 16 , wherein the 1,1-disubstituted alkene composition substantially maintains, over the course of the shelf life, one or more of viscosity and reactivity. 
     
     
         18 : The method according to  claim 1 , wherein the 1,1-disubstituted alkene composition is filled at a relative humidity of about 50% or less. 
     
     
         19 : The method according to  claim 1 , wherein the 1,1-disubstituted alkene composition is filled at a relative humidity of about 10% or less. 
     
     
         20 : The method according to  claim 1 , wherein the 1,1-disubstituted alkene composition further comprises one or more antioxidants and acids. 
     
     
         21 - 24 : (canceled) 
     
     
         25 : The method according to  claim 20 , wherein the 1,1-disubstituted alkene composition comprises between about 5 parts per million or more of the acid and less than 1% by weight of the acid. 
     
     
         26 : (canceled) 
     
     
         27 : The method according to  claim 1 , wherein the 1,1-disubstituted alkene composition comprises one or more of methanesulfonic acid (“MSA”), mono methyl ether of hydroquinone (“MeHQ”), and dibutylhydroxytoluene (“BHT”).
