“…The absence of bands in the range of 2,000-2,300 cm -1 shows that all the diisocyanate groups have reacted completely during polymerization to form urethane linkages and amide groups. 1 H-NMR spectroscopy Figure 5a, b, c show the 1H-NMR spectra of refined sardine fish oil, its alkyd resin and its LO:FO (50:50) interesterification product. The signal assignments are listed in Table 6.…”

“…One of their major drawbacks is the emission of high volatile organic components (VOC) that pollute the ecological system, and hence there is an increasing need to formulate coatings that have zero VOC or to substitute solvents with water. Researchers are engaged in using polymer chemistry to design a water dispersible coating [1][2][3]. Recently, water dispersible polyurethanes have been rapidly gaining importance, mainly due to their easy processing as well as excellent chemical and physical properties, which can be tailored to suit a very wide range of applications.…”

Alkyd and styrenated alkyd resins based on fish oil and their interesterifications with linseed oil were synthesized. The various properties of fish oil, such as its iodine value, acid value, saponification value and moisture content were determined. The interesterification product of fish oil and linseed oil can be used to partially replace the commercially available linseed oil alkyd resin. Alkyd resin and styrenated alkyd resin were modified with 2,2 dimethylolpropionic acid to introduce acid functionality and then sequentially reacted with isophorone diisocyanate, neutralized with amine, chain extended with ethylenediamine and dispersed in water to form a polyurethane dispersion. The newly synthesized resins and polyurethane dispersions were studied for coating properties such as scratch hardness, adhesion, flexibility, impact, solvent and chemical resistance. The polyurethane dispersions exhibited superior coating properties to those of their respective alkyds and styrenated alkyds.
