Abstract
AbstractThe epichlorohydrin‐ethyleneoxide copolymer is modified with 10‐undecenoate and 4‐pentenoate moieties in order to obtain thermosets by cross‐linking through their double bonds. These polymers are then characterized using NMR, IR, chlorine elemental analyses, X‐ray powder diffraction, DSC, TGA, and viscosimetric measurements. Because the thermal crosslinking reaction overlaps in all cases with degradation processes, a free radical source (dicumyl peroxide) is necessary. The Arrhenius kinetic parameters are determined by DSC, using Ozawa and Kissinger expressions. Finally, the quality of cured materials is tested by TGA. © 1995 John Wiley & Sons, Inc.
