“…Trejo-O'Reilly et al [15] showed that the presence of MAA, even in a relatively small amount in several St/BA/MAA batch emulsion polymerization processes led to significant changes in the mechanical properties of the final polymers. Mendizabal et al [16] found that a decrease in pH would increase the amount of MAA incorporated into the latex particle shell, which in turn improved the mechanical properties such as ultimate elongation, ultimate strength, and toughness of the dried latex films.…”

“…Several important studies reported on the partitioning of carboxylic acid monomers between the aqueous and particulate phases [11,12], and the influence of pH on the distribution of acid monomers within the polymer particles, on their surface or in the aqueous phase of the latex [13,14]. The presence of MAA in St/BA emulsion polymerization processes has been shown to lead to significant changes in the mechanical properties of the final polymers [15,16].…”

A three-factor three-level Box-Behnken design was conducted to study the semicontinuous emulsion copolymerization of styrene (St)/butyl acrylate (BA) with methacrylic acid (MAA). The effects of St/BA ratio, MAA content, and pH on the carboxylic acid distribution in the latex, the polymer glass transition temperature (T g ), the average latex particle diameter, the molecular weight and distribution of the polymer products, and the coating adhesion to a polycarbonate substrate were investigated. The experimental results showed how the pH affected the distribution of MAA in the polymer particles. Regression analysis revealed how the St/BA ratio, MAA content, and pH influence the copolymer T g , the latex particle size, the number-average molecular weight M n as well as the weight-average molecular weight M w . An empirical model to correlate the pull-off adhesion of the latex coating to a polycarbonate substrate was developed.

“…There is a great interest for improved acrylic polymers made by emulsion polymerization, capable of forming nonporous homogeneous films. These polymers have applications in paints, adhesives, the manufacturing of wax, paper, and textiles, and in other materials of daily use. − To improve the mechanical properties of acrylic polymers and to increase their compatibility with other materials and their adhesion to substrates, especially to those that are prone to corrosion, these polymers are being modified with small amounts of functional monomers such as N -methylolacrylamide or acrylic, methacrylic, or itaconic acids. , …”

Core−Shell Polymers with Improved Mechanical Properties Prepared by Microemulsion Polymerization

et al. 1999

The synthesis of core−shell polymers of styrene and butyl acrylate by a two-stage microemulsion polymerization process is reported. The microemulsion polymerization was optimized by adding more monomer in a semicontinuous fashion to the latex resulting from the polymerization of the parent microemulsion to produce a high-solid-content polystyrene latex (ca. 40% solids) with small particle size (<30 nm) and high molar mass (>2 × 106 g/mol). Core−shell polymers were characterized by transmission electron microscopy, quasielastic light scattering, IR spectroscopy, differential scanning calorimetry, and dynamic mechanical thermal analysis. The effect of adding a functional monomer (itaconic acid) on the mechanical properties (Young modulus, ultimate elongation, and hardness) of the microemulsion-made structured polymers is also reported. The core−shell polymers synthesized by microemulsion polymerization are more rigid and harder than core−shell polymers of similar composition made by emulsion polymerization. The presence of the functional monomer improves even more the mechanical properties of these materials.
