Benzylidenecyanoacetates having a structure represented bywherein each R4 and R5 is the same or different and is selected from alkoxy, alkyl or alkyl ether. These benzylidenecyanoacetates are liquid at room temperature, have low volatility and are odor free and, thus, are useful in formulating adhesives and coatings.There is also provided a method for making a benzylidenecyanoacetate having a structure represented by formula Bthe method including:(e) reacting an alkyl cyanoacetate with a benzaldehyde to produce an alkyl benzylidenecyanoacetate and then(f) reacting the resulting alkyl benzylidenecyanoacetate with a hydroxy-functional reactant to produce the benzylidenecyanoacetate of formula B,wherein R6 is an alkyl, alkoxy, alkyl ether or a polymer backbone residue moiety.
