摘要：
A process comprising contacting a stable aqueous dispersion of pre-formed polymer particles with a monomer emulsion under emulsion polymerization conditions to form a stable aqueous dispersion of pre-formed polymer particles protuberating from polymer particles arising from 5 the polymerization of the monomer emulsion, wherein the pre-formed polymer particles comprise, based on the weight of the pre-formed polymer particles: a) 2 to 10 weight percent structural units of a phosphorus acid monomer or a salt thereof, b) from 0.2 to 20 weight percent structural units of a carboxylic acid monomer or a sulfur acid monomer or a salt thereof or a combination thereof; and 10 c) from 0.1 to 30 weight percent structural units of a multiethylenically unsaturated monomer; and d) a sufficient proportion of structural units of one or more polymerizable ethylenically unsaturated bulk monomers so that the pre-formed polymer particles have a Tg in the range of from -50 'C to 75 'C; and 15 wherein the monomer emulsion comprises
