Abstract:
An antifoulant composition comprising (meth)acrylic acid and one or more (meth)acrylate or (meth)acrylamide antifoulant polymers, the antifoulant polymer prepared by polymerisinga) about 5 to 100 mole percent of one or more (meth)acrylate or (meth)acrylamide monomers of formula or a mixture thereof, wherein R1 is independently selected at each occurrence from hydrogen and methyl; R2 is selected from alkyl, aryl, cycloalkyl, alkylaryl, arylalkyl, aminoalkyl, aminoaryl, hydroxyalkyl, alkoxyalkyl, oxoalkyl and haloalkyl; and R3 and R4 are independently selected from hydrogen, alkyl, aryl, alkylaryl, arylalkyl, aminoalkyl, aminoaryl, hydroxyalkyl, alkoxyalkyl, oxoalkyl and haloalkyl, or R3 and R4, together with the nitrogen atom to which they are attached, form a heterocyclyl group; andb) 0 to about 95 mole percent of one or more vinylic monomers.
