Abstract
A methyacryloyl or acryloyl derivative of an ester of cyanoacetic acid may be of the formula: CN—CH2—COOR2OCOCR1═CH2. R1 may be H or CH3, and R2 may be one of the group of moieties including alkyl, alkenyl, alkynyl, alkoxyalkyl, poly (oxyalkyl), aryl, cycloalkyl, and heterocyclyc radical, or substitited combinations thereof. Further, R2 may include between 1 and 16 carbon atoms or heteroatom ring members.
