| Abstract: | PP EPR and PP EPR PP copolymers were synthesized by sequential changing olefin monomers in a slurry of δ T iCl 3 Et 2AlCl hexane. Experiments showed that the polymer chain was living within 100 minutes. By means of measurement of dynamic and internal friction spectra,it was demonstrated that PP EPR and PP EPR PP only have one glass transition temperature ( T g) respectively,and each of them showed good compatibilization for PP/EPT blend. All these indicate that it is possible to prepare di block and tri block copolymers of ethylene and propylene in sequential polymerization of olefin with Ziegler Natta catalyst. |
