Abstract

This invention relates to novel electron deficient olefins, such as certain 2-cyanoacrylates and methylidene malonates, prepared using an imine or an iminium salt.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . Compounds according to  claim 1 , selected from the group consisting of 
       
         
           
           
               
               
           
         
       
     
     
         2 . A composition comprising:
 (a) one or more compounds of  claim 1 ;   (b) a stabilizer package comprising at least one of a free radical stabilizer and an anionic stabilizer; and   (c) optionally, one or more additives selected from the group consisting of cure accelerators, thickeners, thixotropes, tougheners, thermal resistance-conferring agents, and plasticizers.   
     
     
         3 . The composition of claim  10 , further comprising a coreactant. 
     
     
         4 . The composition of claim  11 , wherein the coreactant is a member selected from the group consisting of epoxides, episulfides, oxetanes, thioxetanes, dioxolanes, dioxanes, isocyanates, maleimides, oxazolines, (meth)acrylates, acrylamides, cyanoacrylates, methylidene malonates, and vinyl ethers.
