摘要:
The invention relates to an exhaustion agent, which is an aqueous emulsion of polymerized monomers, wherein the monomers contain: (meth)acrylic acid (MAA); alkyl (meth)acrylate, such as methyl (meth)acrylate (MMA); and a substituted or unsubstituted styrene; and having an average particle size of the emulsified particles is less than about 220 nm.
