PROPYLENE COPOLYMERS CONTAINING STYRENE UNITS |
摘要 |
Isotactic-polypropylene-based copolymers having a homogeneous distribution of recurring units of formula (1) where R is a hydrogen, halide radical or hydrocarbyl radical optionally containing an atom selected from oxygen, nitrogen, sulphur, phosphorus and silicon and n is an integer ranging from 1 to 3; said copolymer having a <13>C-NMR spectrum wherein the resonance signals attributable to the links between different monomeric units fall around 30, 34, 35, 45 and 47 ppm and present intensities at least two times higher than the resonance signals attributable to styrene-styrene sequences around 41 ppm and 44-46 ppm. A process for preparing said copolymers carried out in the presence of homogeneous catalytic systems comprising a metallocene compound and a cocatalyst. Functionalized copolymers obtainable from said isotactic-polypropylene-based copolymers. Graft copolymers comprising said isotactic-polypropylene-based copolymers as backbones. |
