COPOLYMERIZATION OF PROPYLENE WITH 1-OCTENE OVER TiCl4/MgCl2 CATALYST
The copolymerization of propylene with 1-octene over TiCl4/MgCl2-Al(i-Bu)3 system has been studied. It was found that the catalytic activity is higher in the case of copolymerization than that of homopolymerization. As the 1-octene concentration increased in copolymerization
the hrxane-insoluble fraction decreased and crystallinity of copolymer decreased to 1%. The monomer reactivity ratios were determined as rp=5.63 and r0=0.32. The monomer composition and sequence distribution of the copolymers were determined by IR and 13C-NMR.
