| Résumé : |
The hybrids, oil/alkyd-acrylic, were synthesized by polymerizing different acrylic monomers in the presence of colloidal oil/alkyd droplets. The presence of oil/alkyd caused retardation in the polymerization through radical delocalization following radical transfer to the unsaturated groups of the fatty acids in the oil/alkyd but the adjustment of reaction condition could give 100% conversion. The homogeneity of the hybrids differed from blends as was observed in good film formation without the use of cosolvents. In some cases a true synergistic behaviour was observed. The mechanism of interaction of resin in the hybrid is discussed. The main objective of this research is to develop a resin system with common characteristics of two or more (if any) resins. The hybrids thus developed have significant improved performance over the blends and the individual system. The application properties of hybrids could be varied over a broad range by changing either the acrylic part or the alkyd part or their ratio. The hybrids were applied on various substrates and their performance were studied. Significant improvement in adhesion, on various substrates gloss and gloss retention, hardness, dirt rebar found. This paper will describe the design, synthesis, characterization and coating performance of the hybrids. |
