  • Resin-fortified sugar-based vinyl emulsion copolymers and methods of preparing the same
    Patent number: 6355734
    Abstract: A method of preparing a resin-fortified polymer emulsion is disclosed. In one embodiment, the method comprises polymerizing at least one monomer in the presence of a surfactant, an initiator, a resin and sugar-based vinyl monomer under emulsion polymerization reaction conditions effective for initiating polymerization, wherein an emulsion polymerization product is formed that comprises a sugar-based vinyl monomer. A composition comprising resin-fortified emulsion polymer comprising a sugar-based vinyl monomer, a resin and at least one emulsion polymerizable monomer is also disclosed. An ink comprising a pigment and a resin-fortified polymer emulsion comprising a sugar-based vinyl monomer, a resin and at least one emulsion polymerizable monomer is also disclosed.
