Abstract
EPDM elastomers have been synthesized by the Ziegler-Natta oatalytic system VOCl3/Al2Et3Cl3 with the objetive of verifying the influence of termonomers on terpolymer synthesis and on the properties of peroxide-vulcanized terpolymer compositions. Two groups of termonomers have been studied. Dienes, i.e., dicyclopentadiene (DCP), 5-ethylidene-2-norbornene (ENB) and limonene, and aromatic compounds, i.e., indene (IND) and styrene (ST). The influence on the synthesis has been verified by yield, termonomer incorporation, and molecular weight distri bution. The vulcanizate properties have included mechanical and electrical properties.
