Acrylic Resin Adhesive

The acrylic resins may be considered as belonging to the vinyl family. Compounds with the prefix “acryl” may be divided into two classes: the first comprising those derived from acrylic acid, and the second, acrylonitrile and acrylamide. The term acrylic or acrylate is conventionally reserved for compounds of the former class and polymers derived from them. Acrylonitrile, which is vinyl cyanide, and the acrylamide are so called because they are respectively the precursor and amide of acrylic acid, but neither of these monomers or their polymers are conventionally designated acrylics. The acrylic of acrylate monomers have the general formula.

CH2=CCH3COOCH2

And the most important members of this class are acrylic acid and methacrylic acid (R=H or CH2 and R’=H) and their esters with the lower aliphate alcohols (R’=alkyl)
