Abstract
A composition comprising a polypropylene copolymer containing 0.5-7 mol % ethylene comonomer an having an MFR of 5-50 g/10 min and a relative proportion of isolated and block comonomer sequences in the polypropylene (I(E)) in the range of 5-40 is disclosed, wherein I(E) is defined as I(E)=f/((f+f+f))*100 in which I(E) is the relative content of isolated to block ethylene sequences (in %); fis the mol fraction of propylene/ethylene/propylene sequences (PEP) in the sample; fis the mol fraction of propylene/ethylene/ethylene sequences (PEE) and of ethylene/ethylene/propylene sequences (EEP) in the sample; and fis the mol fraction of ethylene/ethylene/ethylene sequences (EEE) in the sample, all sequence concentrations being based on a statistical triad analysis ofC-NMR data. The composition preferably comprises a blend of a propylene homopolymer and a propylene-ethylene copolymer, and the propylene-ethylene copolymer is preferably a polypropylene post-consumer resin (PCR).
