低挥发性有机化合物，低成本的一些水性聚合物分散剂

LOW- VOC, LOW COST COALESCENT FOR CERTAIN AQUEOUS POLYMERIC DISPERSIONS
摘要：
A coalescent consisting essentially of a residue from a process for forming propyleneglycol phenyl ether, the coalescent consisting essentially of 65%-75% by weight, based on the weight of the residue, dipropyleneglycol phenyl ether, 8%-10% by weight, based on the weight of the coalescent, monopropyleneglycol phenyl ether, 4%-6% by weight, based on the weight of the coalescent, tripropyleneglycol phenyl ether, and 0.1%-10% by weight, based on the weight of the coalescent, alkalinity(reported as NaOH) is provided. Also provided is a method for forming certain low-VOC, low cost, coalesced aqueous polymeric dispersions including, as copolymerized units, from 70% to 100% by weight, based on the solids weight of the aqueous polymeric dispersion, vinyl acetate monomer and an aqueous coating composition including the coalesced aqueous polymeric dispersion.
