Abstract
There is disclosed an antifoam component which includes at least one poly(acrylate) copolymer for use in a fuel. Poly(acrylate) polymers prepared by polymerizing a (meth)acrylate monomer comprising C1 to C30 alkyl esters of (meth)acrylic acid (“multifunctional monomer”) are also disclosed. Other poly(acrylate) polymers prepared by polymerizing (i) a (meth)acrylate monomer comprising C1 to C4 alkyl esters of (meth)acrylic acid (“solubility monomer”); (ii) a (meth)acrylate monomer comprising C5 to C12 alkyl esters of (meth)acrylic acid (“surface tension monomer”); and (iii) optionally at least one additional monomer comprising a solubility monomer, a surface tension monomer, a monomer comprising C1 to C30 alkyl esters of (meth)acrylic acid (“multifunctional monomer”), or combinations thereof are also disclosed.
