Synthesis and Property of Water-Soluble Hyperbranched Polyacrylate Emulsion
Hyperbranched polymer is a kind of non-linear polymers with highly branched structure and a lot of terminal groups.It has many advantages,such as high reactivity,good solubility and low viscosity.Hyperbranched polymer has become a focus in modem scientific domain.In this paper,polyester-type water-soluble hyperbranched monomer is prepared by the ring-opening polymerization reaction of maleic anhydride with polyol.Hyperbranched polyacrylate emulsion with 70-110nm was synthesized by emulsion polymerization using methyl methacrylate (MMA),butyl acrylate (BA),acrylic acid (AA) and hyperbranched polymer as comonomer.The effects of dosages and adding order of monomers,concentration of initator,type and amount of chain transfer agent on the polymerization are discussed.The as-prepared emusions were analyzed by FTIR,DSC,SEM.The solid content,particle size,stability of emulsion and morphology and water absorption of film were measured.The results showed that hyperbranched polyacrylate emulsion had low viscosity,high stability and can form very flat and smooth film.Hyperbranched polyacrylate emulsion can be widely applied in modem ink industry for its low cost,simple process and stable quality.
