Crosslinkable dextrin-coated latex via surfactant-free emulsion polymerization

Emulsion polymerization remains the most attractive method to produce waterborne dispersions for coatings and adhesives, thanks use of water as dispersion medium. The possibility replace surfactants necessary stabilization by biopolymers would make this route even more alleviate shortcomings surfactants. Herein, dextrins were used sole stabilizer stable latex emulsion with solid contents up 55 wt% narrow size distributions. H2O2/ascorbic acid redox initiator was found be effective, ensuring a complete at 50 °C within 3–4 h, giving rise dextrin-functionalized polymer latexes particle between 150 600 nm. explained coating particles chemically bound layer dextrins, forming steric barrier. functionalization exploited induce post-crosslinking inclusion additives capable reacting dextrins. As application, crosslinkable pressure-sensitive adhesive prepared without any additive. Given biobased origin their availability, in is promising coatings, inks, drug delivery, textiles.
