Abstract:
1. A modified polyolefin, obtained by functionalization of a unfunctionalized polyolefin which is obtained by polymerizing a monomer composition, comprising: ethylene in a proportion of not more than 20% by mass; propylene in a proportion of either 50-98% by mass or not more than 15% by mass; and 1-butene in a proportion of 87-98% by mass or not more than 55% by mass; wherein a sum of the proportions is 100% by mass and the unfunctionalized polyolefin comprises no components of <500 D, a triad distribution for the propylene in the unfunctionalized polyolefin comprises: a triad distribution for the 1-butene in the unfunctionalized polyolefin comprises: the triad content is determined by the sum of isotactic, syndiotactic and atactic triads of propene and 1-butene each add up to 100%, the unfunctionalized polyolefin is obtained by polymerization with a metallocene catalyst, and functionalizing the unfunctionalized polyolefin comprises grafting one or more monomers having one or more functional groups onto the unfunctionalized polyolefin.
