Abstract The need for the production of synthetic polymers from renewable and sustainable resources also affects area emulsion polymerization. bio-based monomer (BM) was synthesized camelina oil (CO) itaconic acid through transesterification epoxidation CO, followed by itaconation, resulting in a blend methyl esters CO-originated fatty acids functionalized with reactive itaconate groups. Various amounts BM were copolymerized standard acrylic monomers (0−30 wt. % mixture) using polymerization technique to obtain film-forming latexes. Infrared Raman spectroscopies evidenced successful incorporation into structure latex polymers. ultra-high molar mass nanogel fraction detected asymmetric flow-field flow fractionation coupled multiangle light scattering (AF4-MALS) comprising copolymers; higher content, more extensive fraction. Crosslinking induced testified reactivity itaconated functions provided additional evidence copolymerization ability BM. resulted hardness glass transition temperature enhancement (about 11% 9°C, respectively, case 30 content contrast 0 copolymer). Coatings excellent transparency gloss obtained all latexes regardless used. Slightly increased water repellency 7 ° contact angle value) significantly improved whitening resistance coatings 80% decreased after 1-day long exposure) found copolymer, where phenomenon highly dependent on content.
