acrylic acids

a·cryl·ic ac·ids

(ă-kril'ik as'idz),
A series of unsaturated aliphatic acids of the general formula R=CH-COOH; the prototype, acrylic acid (R = CH2) or 2-propenoic acid, is derived from propionic acid by reduction or from glycerol by dehydration.

Summary: Acrylic acid was polymerized and modified with some acids such as salicylic acid, benzalthiobarbituric acid and some amines such as aniline and [alpha]-naphthylamine.
