SHORT OIL ALKYD RESIN BASED POLYMERIC SURFACTANT

摘要

Novel polymeric surfactants based on short oil alkyd have been synthesized in a laboratory. Alkyd resins were investigated by selecting different compositions based on Linseed oil, glycerol, phthalic anhydride, maleic anhydride, rosin and benzoic acid. The sodium bisulphate and sodium bisulphite are taken as catalyst to enhance the rate of reaction. The polymer then evaluated for physicochemical properties such as molecular weight (Mw), foam Volume (ml), Surface tension (p) and HLB ratio by standard methods.The polymers so obtained have molecular weight of 3,241. The polymers have been systematically analyzed for spectral Properties. The IR and NMR spectral study shows the presence of ester, ether, free hydroxyl and free acid group in the polymer. This polymer is found to be useful in formulation of liquid and powder detergent.
