RANDOM COPOLYMER OF PROPYLENE WITH 1-HEXENE |
摘要 |
A propylene and 1-hexene copolymer containing from 0.5 wt % to less than 5 wt % of 1-hexene derived units said copolymer having: a) a melting point higher than 145° C.; b) a melt flow rate (MFR2) determined according to ISO method 1133 (230° C., 2.16 kg ranging from 10 dl/10 min to less than 60 dl/10 min; said copolymer being chemically degradated to MFR2 and wherein the ratio MFR2/MFR1 is comprised between 15 and 56; wherein MFR1 is the melt flow rate measured according to ISO method 1133 (230° C., 2.16 kg) of the propylene/1-hexene copolymer before the degradation |
