Sustainable Polymer Latexes based on Linoleic Acid for Coatings Applications with Chemspeed’s Automated MULTIPLANT POLY

The synthesis of new waterborne polymer latexes based on renewable linoleic acid (LA) was investigated. Methacrylic functionality was incorporated into the LA and the resulting monomer was successfully polymerized via miniemulsion polymerization. The effect of the initiator amount and type on microstructure was analyzed. Almost totally converted latexes with different microstructures were achieved. Furthermore, the effect of the presence of labile allylic hydrogens on the LA backbone was discussed in terms of microstructural properties, as well as final film properties. The results suggested that LA based latexes have great potential to replace petroleum based waterborne coating materials.
