Three methods were used to prepare polysiloxane-functionalized acrylic latexes via emulsion polymerization. Ethyl acrylate and 2-ethylhexyl acrylate were used in all three methods as the acrylic phase. In the first method, an acrylic core was prepared with addition of a coupling agent, 3-(trimethoxysilyl) propyl methacrylate, after which a cyclic siloxane monomer (octamethylcyclotetrasiloxane) was reacted with the coupling agent. In the second method, a silane-terminated polysiloxane (H-PDMS) was reacted with ethylene glycol dimethacrylate, and then copolymerized with ethyl acrylate and 2-ethylhexyl acrylate in a batch emulsion polymerization. In the third method, cyclic siloxane monomer was added during emulsion polymerization of ethyl acrylate, 2-ethylhexyl acrylate, and 2-hydroxyethyl methacrylate. Particle size distribution and particle morphology were evaluated using dynamic light scattering (DLS) and transmission electron microscopy (TEM), respectively. A core-shell morphology was observed in TEM for the first preparation method as proposed. After film formation, surface tension, morphology and dynamic mechanical properties were investigated. Stratification was also examined by Fourier-transform infrared spectroscopy (FT-IR) and energy dispersive X-ray (EDX). Microphase separation was observed by atomic force microscopy (AFM) after polysiloxane modification. Energy dispersive X-ray data indicated that only the second preparation method had a higher silicon content at the film-air interface than film-substrate interface. In all methods, the storage modulus and surface energy of latex films decreased after polysiloxane modification.
