研究了丙烯与双(6-庚烯基)锌(BHZ)催化的byrac-Me2Si[2-Me-4-Ph-Ind]2ZrCl2/MAO的聚合反应。 BHZ既充当共聚单体又充当链转移试剂，这通过1H NMR和13C NMR谱验证。 LCB 的生产解释了 BHZ 对产品分子量和流变特性的新影响。
The polymerization of propylene combined with bis(6-heptenyl)zinc (BHZ) catalyzed byrac-Me2Si[2-Me-4-Ph-Ind]2ZrCl2/MAO was investigated. BHZ acts as both a comonomer and a chain transfer reagent, which was verified by1H NMR and13C NMR spectra. A novel effect of BHZ on the molecular weight and rheologic properties of the product was explained by the production of LCB.
