Water-borne coatings systems
"Two water-reducible polymers were synthesized by free-radical polymerization. A low molecular weight polymer (22,000) and a high molecular weight polymer (118,000) polymer based on methyl methacrylate (MMA), methacrylic acid (MAA), and butyl methacrylate (BMA) were synthesized. Properties of each polymer were characterized and studied. For each polymer, the glass transition (Tg), was determined. Several coalescent solvents were used to examine the effectiveness of each, on lowering the Tg of the two polymers. These experiments showed that texanol and E.B. performed the best. Viscosity profiles were run on polymer solutions containing both polymers at a range of 1%-4% coalescent aid. The viscosity profiles demonstrated that at higher levels of coalescent solvents, the viscosities became unstable. From the viscosity profile data, two paints were formulated. The general coatings were formulated to demonstrate the effect of coalescent aid on high molecular weight polymers and low molecular weight polymers. The results of testing demonstrated that there are trends and similarities between the two paints"--Abstract, leaf iii.
