Abstract
Poly(tri-n-butyltin) methacrylate, an anti-fouling compound, is prepared by sterifying a cross-linked polymethacrylic acid with tributyltin oxide in the presence of a poly solvent. The poly solvent, such as acetone, dioxane or methyl-ethyl ketone, causes particle size reduction due to hydraulic shattering. The in-reaction particle size reduction eliminates the need for mechanical post grinding in the current process.
