Abstract
Official abstract text for this publication.
The present disclosure relates to a propylene-1-hexene copolymer having: i) a content of 1-hexene derived units ranging from 0.6 wt % to 3.0 wt %; ii) a melt flow rate (MFR) measured according to the method ISO 1133 (230° C., 5 kg) ranging from 0.5 g/10 min to 5.0 g/10 min; iii) a polydispersity (PI) ranges from 4.5 to 10 and the distribution of molecular weight is of multimodal type; iv) a melting point ranging from 160° C. to 145° C.; and v) a differential scanning calorimetry (DSC) curve (temperature/heat of fusion) that shows at least two peaks.
First claim
Opening claim text (preview).
What is claimed is: 1. A propylene-1-hexene copolymer having: i) a content of 1-hexene derived units ranging from 0.6 wt % to 3.0 wt %; ii) a melt flow rate (MFR) measured according to the method ISO 1133 (230° C., 5 kg) ranging from 0.5 g/10 min to 5.0 g/10 min; iii) a polydispersity index (PI) ranging from 4.5 to 10 where the distribution of molecular weight is of a multimodal type; iv) a melting point ranging from 145−160° C.; and v) a differential scanning calorimetry (DSC) curve (temperature/heat of fusion) that shows at least two peaks. 2. The propylene-hexene-1 copolymer according to claim 1 , wherein the content of 1-hexene derived units ranges from 0.7 wt % to 2.0 wt %. 3. The propylene-hexene-1 copolymer according to claim 1 , wherein the melt flow rate (MFR) measured according to the method ISO 1133 (230° C., 5 kg) ranges from 0.6 g/10 min to 4.0 g/10 min. 4. The propylene-hexene-1 copolymer according claim 1 , wherein the melting point ranges from 147-155° C. 5. An industrial sheet comprising the propylene-1-hexene copolymer of claim 1 .
