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. © 1997 John Wiley & Sons, Inc.
