摘要： An emulsion polymer comprising: (a) structural units of a specific polymerizable surfactant, (b) structural units of an ethylenically unsaturated anionic monomer, and (c) structural units of an ethylenically unsaturated nonionic monomer; wherein polymer segments of the emulsion polymer that comprise structural units of the ethylenically unsaturated anionic monomer and structural units of the ethylenically unsaturated nonionic monomer together have specific Hansen solubility parameters. An aqueous coating composition comprising such emulsion polymer provides good early water blister resistance.

摘要： The present invention provides aqueous polymer compositions containing one or more, or, preferably, two or more markers selected from a C1-C12 alkyl phenyl ether having a formula Ph(R2)m(OR1)n, wherein Ph is an aromatic ring containing group having from six to nine carbon atoms, R1 is a C1-C12 alkyl group, R2 is a C1-C12 alkyl group, m is an integer of from 0 to 5, n is an integer of from 1 to 3, and (m+n) is an integer of from 1 to 6. The markers are readily detectable, such as by mass spectroscopy, upon solvent extraction and separation from the aqueous polymer compositions, or from dried or cured coatings, film or layers thereof.
