Research on Synthesis of Neutral Sizing Agent by Soap-Free Emulsion Polymerization

Abstract:

In this paper, a sizing agent applied in papermaking was synthesized via emulsion polymerization using styrene (St), methyl acrylic acid (MAA), methyl methacrylate (MMA) and butyl acrylate (BA) as monomer. In this process, potassium persulfate (KPS) was used as a initiator and sodium lauryl sulfate (SDS) and OP-10 were used as the emulsifier or no emulsifier was used, while NB₂_B was used as a protective atmosphere for the reaction system. The product of emulsion polymerization with St and BA has a good comprehensive properties and a certain sizing effectiveness. Furthermore, the microwave irradiation could not only produce emulsions with small diametric particles but also shorten the polymerized time greatly.
