Spectroscopic characterization of linseed oil based polymer nano-composites

Conjugated linseed oil based nano-composites from thermal polymerization have been investigated quantitatively through 1H NMR and FTIR spectroscopic techniques. The solubility of samples measured by soxhlet extraction ranges from 28 to 55% for varying linseed oil content (30-70%) and 28 to 43% for the samples with varying montmorillonite clay content (0-10%). The content of grafted linseed oil calculated from 1H NMR results ranges from 2 to 19% with varying oil content (30-70%) and 7 to 22% with varying clay content (0-10%). The FTIR results show variation in grafted linseed oil content from 2 to 19% with varying oil content (30-70%) and 6 to 23% with varying clay content (0-10%). The clay embedded in the polymer matrix, calculated from FTIR results, ranges from 3 to 5% with varying oil content (30-70%) and 0 to 8% with varying clay content (0-10%).
