✦ Synopsis

The syntheses of cardanol-glycols (CGs) and CG-based polyurethane (CGPU) films have been investigated. The characterization of CGs and CGPU films were determined by IR, 1 H-NMR spectra as well as a swelling test and DSC studies. The increase of molecular weight of glycols leads to a decrease of cardanol content in CGPUs and hence decreases crosslinking density of the films, which strongly affects the swelling property and glass transition temperature. The autooxidation-polymerization of CGPUs through the double bonds of the cardanol side chain, catalyzed by cobalt salt, resulting the crosslinking films was also discussed.

Polyurethane films were prepared from the reaction of cardanollignins (CL) with a different cardanolpignin ratio and toluene diisocyanate. The crosslink density, the glass transition temperature and the mechanical properties of the obtained films were also determined. The increase of cardanol conten
