Nucleated c3c4 copolymers |
| abstract |
A propylene copolymer composition comprising A) a propylene butylene copolymer which is -free of phthalicacid esters as well as decomposition products thereof; -obtained by a Ziegler-Natta catalyst and B) at least one α-nucleating agent, the propylene copolymer composition having -a MFR (2.16kg/210°C) in the range of 2 to 100 g/10min -a melting point Tm(1) of less than 140°C -a melting point Tm(2) of at least 150 °C, said Tm(2) being associated with more than 75% of the total melting enthalpy and whereby the propylene copolymer -has monomer units derived from a) propylenein an amount of 90.0-98.0 mol.-% b) butylenein an amount of 2.0-10.0 mol.-% with respect to the total weight of the propylene butylene copolymer -an isotacticity mm% as determined by 13C NMR spectroscopy of below 99.0 %; and -a Koenig-B parameter with respect to butylene as determined by 13C NMR spectroscopy of more than 0.98. |
