POLYMERS FROM RENEWABLE RESOURCES .8. THERMAL-PROPERTIES OF THE INTERPENETRATING POLYMER NETWORKS DERIVED FROM CASTOR OIL-ISOPHORONE DIISOCYANATE-POLYACRYAMIDES
Castor oil was reacted with isophorone diisocyanate varying the isocyanate/hydroxyl ratio to produce a number of polyurethanes (PUs). All the PUs were reacted with acrylamide and methacrylamide using ethylene glycol dimethacrylate as the crosslinker and benzoyl peroxide as the initiator. Thermogravimetric analysis of the polymers was conducted using a computer analysis method for assigning the kinetic mechanism. The degradation steps have been discussed in the light of the kinetic parameters. (C) 1995 John Wiley & Sons, Inc.
