Title: Preparation of fluorine-containing starch paper sizing agent by inverse emulsion polymerization
Abstract: A fluorine-containing starch paper-sizing agent is prepared from cationic tapioca starch substrate and a fluorine-containing monomer with ammonium sulfite as initiator and S200 as emulsifier through inverse emulsion copolymerization.The influences of synthetic conditions on the graft copolymer are studied.The optimal conditions of preparation are obtained as follows:95.23 mmol/L of the initiator,2∶2.5 of the rate of F-containing monomer to starch,45℃ of reaction temperature,4 hours of reaction time.Under above optimal conditions the grafting percentage can be 83.52%,with a grafting efficiency of 85.57% and monomers conversion ratio of 87.89%.
