NOVEL BENZYLIDENECYANOACETATES AND A METHOD FOR MAKING BENZYLIDENECYANOACETATES.

摘要

Benzylidenecyanoacetates having a structure represented by (A) wherein 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 (B) the method including: (e) reacting an alkyl cyanoacetate with a benzaldehyde to produce an alkyl benzylidenecyanocetate 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.
