“…Very water soluble or water insoluble comonomers (Figure 6.6) that do not diffuse into the polymerization locus before free radical polymerization occurs, broadens the chemical composition distribution and in extreme circumstances, generates two distinct polymers in separate particle populations. Figure 6.6 displays water solubility values of monomers commonly used in latexes, along with two fatty acids for comparison [46,47,48,49]. Fatty acids have negligible water solubility due to the presence of eighteen nonpolar carbons incapable of hydrogen bonding.…”

“…The synthesis of such multiple phase composite particles provides an opportunity to tailor properties for a range of desired applications such as paints, coatings, and additives. 8,9 These latexes may be used to create latex films with properties that cannot be achieved by a physical blend of two or more different polymer components. For example, binders used in coatings need to fulfill contradictory demands such as excellent film formation and appearance and good blocking resistance and hardness.…”

A series of core-shell polymeric particles with poly(n-butyl acrylate-co-methacrylic acid-coethylene glycol dimethylacrylate) as core and poly(styrene-co-methyl methacrylate) as shell were prepared by seeded emulsion polymerization. The role of ethylene glycol dimethylacrylate (EGDMA) is to crosslink the core so as to avoid any probability of gel formation and to bind both the core and the shell phase together. The spherical morphology of the core-shell structure was achieved at 60:40 core to shell ratio. The core-shell morphology was confirmed by SEM and TEM analyses. GPC analysis of the particles reveals that the polymer shows a bimodal mode. The first peak has M w = 382700 and M n = 245200 with polydispersity index of 1.6, and the second peak has M w = 21200 and M n = 14800 with polydispersity index of 1.4. These core-shell latexes were applied as a pigment/binder in emulsion paint and the paint properties like gloss, rock hardness, washability, opacity, etc. were compared with the standard. The results show that these coreshell latexes can provide similar hiding power with 17% reduction of TiO 2 in the paint formulation.

“…The use of water as a dispersed medium has been considered an environmentally friendly process and is ideal for polymerizing biobased monomers [ 7 ]. For example, the synthesis of protective coatings based on branched vinyl esters [ 8 ], self-crosslinkable prepolymers of lauryl methacrylate with trimethylolpropane trimethacrylate [ 9 ], and the synthesis of terpene-based methacrylate copolymer [ 10 ].…”

Dibutyl Itaconate and Lauryl Methacrylate Copolymers by Emulsion Polymerization for Development of Sustainable Pressure-Sensitive Adhesives

Renewable polymers possess the potential to replace monomers from petrochemical sources. The design and development of polymeric materials from sustainable materials are a technological challenge. The main objectives of this study were to study the microstructure of copolymers based on itaconic acid (IA), di-n-butyl itaconate (DBI), and lauryl methacrylate (LMA); and to explore and to evaluate these copolymers as pressure-sensitive adhesives (PSA). The copolymer synthesis was carried out through batch emulsion radical polymerization, an environmentally friendly process. IA was used in a small fixed amount as a functional comonomer, and LMA was selected due to low glass transition temperature (Tg). The structure of synthesized copolymers was studied by FTIR, 1H-NMR, Soxhlet extraction, and molecular weight analyses by GPC. Furthermore, the viscoelastic and thermal properties of copolymer films were characterized by DMA, DSC, and TGA. The single Tg displayed by the poly(DBI-LMA-IA) terpolymers indicates that statistical random composition copolymers were obtained. Moreover, FTIR and NMR spectra confirm the chemical structure and composition. It was found that a cross-linked microstructure and higher molecular weight are observed with an increase of LMA in the feed led. The Tg and modulus (G′) of the copolymers film can be tuned with the ratio of DBI:LMA providing a platform for a wide range of applications as a biobased alternative to produce waterborne PSA.
