Abstract
An improved process for preparing core/shell MBS modifiers is disclosed, wherein by adding feeds of the monomers which form the second and/or third stage polymers prior to completion of polymerization of the earlier stages, a process with substantially reduced polymerization time results with no loss in properties of the product. The process further includes agglomeration of the rubbery polymer to increase particle size during the polymerization process.
