Abstract
Methods of producing a latex, and the resulting latexes, are described herein. Bio-based colloidal particles are used in a free radical polymerization process. The particles may provide one or more of a seed particle, stabilizing agent, Pickering emulsifier, surfactant or co-monomer. Optionally, the particles (or biopolymer molecules such as starch in the particles) are functionalized, for example to provide double bonds or free radicals, prior to or while conducting a free radical polymerization reaction including the particles and a second compound which is a monomer. In another option, the particles are used in the presence of a functionalizing agent (capable for example of providing double bonds or free radicals on a biopolymer) in a free radical polymerization reaction. Optionally, the resulting latex may include particles of a mixed morphology including a bio-based phase. Methods of functionalizing bio-based particles and, in some cases, resultant particles (intermediate reaction products) are also described.
