Abstract A number of semi‐interpenetrating polymer networks (semi‐IPNs) were synthesized by reacting polyurethanes (prepared from castor oil and various diisocyanates) and a phenolic resin (prepared from cardanol and furfural) The physico‐chemical properties of the semi‐IPNs have been investigated. The thermogravimetric analysis of polymers was followed using a computer analysis method for assigning the kinetic mechanism. Various kinetic equations have been used to evaluate the kinetic parameters. The suggested mechanism of degradation of the semi‐IPNs is based on the kinetic parameters.
