Popis:	Propylene polymerization with Ind2Zr(OFl)Cl, where Ind=indenyl and OFl=deprotonized moiety of fenchyl alcohol (1,3,3-trimethyl bicyclo[2.2.1]heptan-2-ol) was investigated. The catalyst is capable to polymerize the monomer producing elastomeric propylene–ethylene copolymers containing blocks of ethylene units and atactic propylene sequences. The amount of ethylene units is controlled by the reaction conditions and up to 35.4 mol% ethylene could be obtained. The copolymers with high ethylene sequences content crystallizes resulting in melting transitions in the range of 120 °C.
