摘要

(Mw / Mn) of from 1.8 to 3.5 g / mol and a molecular weight (Mw) of from 75,000 to 350,000 g / mol and a MFR of 230/56 MFI of from 5 to 1000 g / Having a viscosity of from 0 to 300 cm 3 / g, a melting point of from 120 to 165 ° C, an isotactic block length of from 25 to 150 and an ether extract of less than 2% by weight based on the total weight of the polymer ^a -CH = CH-R ^b wherein R ^a and R ^b are the same or different and each is hydrogen or a straight chain or branched C ₁ -C ₁₅ -alkyl, or R ^a and R ^b are each a bond To form a ring system together with the atoms to which they are attached and a polyolefin formed from ethylene or from 0 to 10% by weight of a second olefin as comonomer as mentioned above.
