Abstract
A number of semi-interpenetrating polymer networks (semi-IPNs) were sy nthesized by reacting polyurethanes (prepared from castor oil and vari ous diisocyanates) and a phenolic resin (prepared from cardanol and fu rfural). The physico-chemical properties of the semi-IPNs have been in vestigated. The thermogravimetric analysis of polymers was followed us ing a computer analysis method for assigning the kinetic mechanism. Va rious kinetic equations have been used to evaluate the kinetic paramet ers. The suggested mechanism of degradation of the semi-IPNs is based on the kinetic parameters.
