Recent work has indicated that cyclic, higher Tg, methacrylate monomers that are incorporated into a styrene/acrylic copolymer may be effective in reducing solution viscosity. This work will discuss the effect of incorporating different cyclic methacrylate monomers on solution viscosities of several styrene/acrylic polymers. The high Tg cyclic monomers studied were : isobornyl methacrylate, cyclohexyl methacrylate, t-butylcyclohexyl methacrylate, and 3,5,5-trimethylcyclohexyl methacrylate. The monomers were incorporated into two polymers of different Tgs (30°C and 60°C) at between 60-65% solids level. Viscosities were measured and distinct differences in solution viscosities were noted. The polymers were characterized by various measurements. This paper will discuss these observations and the impact that this data provides. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=18486
