Novel terpolymers with a reactive moiety were synthesized using coordination polymerization with a metallocene catalyst and a cocatalyst system. C2-symmetric rac-Et(Ind)2ZrCl2 and tri-iso-butylaluminum/dimethylanilinium tetrakis (pentafluorophenyl) borate were used as the catalyst and cocatalysts, respectively. We synthesized reactive terpolymers consisting of ethylene, a high α-olefin (1-hexene, 1-octene, 1-decene, and 1-dodecene), and divinylbenzene. The structure and composition of the terpolymers were examined by 1H nuclear magnetic resonance analysis. The catalytic activity, polymer yield, molecular weight, and molecular weight distribution were analyzed as functions of the chain length and content of high α-olefin. The thermal properties and crystallinity were determined using differential scanning calorimetry and wide-angle X-ray scattering. |
