Abstract

Official abstract text for this publication.

A terpolymer containing propylene, ethylene and an alpha olefins of formula CH2═CHZ wherein Z is an hydrocarbon group having from 2 to 10 carbon atoms wherein: (i) the content of ethylene derived units ranges from 0.5 wt % to 5.0 wt %; (ii) the content of alpha olefin derived units ranges from 1.0 wt % to 5.0 wt %; (iii) the amount (Wt %) of alpha-olefin (C6), the amount (Wt %) of ethylene (C2) and the melting point (Tm) of the terpolymer fulfil the following relation (1) Tm>−(C2+0.8C6)*6+157 (1) (iv) the polydispersity index (PI) ranges from 3 to 8.

First claim

Opening claim text (preview).

The invention claimed is: 1. A terpolymer comprising: (i) 1.0 to 3.0 wt %, based upon the total weight of the terpolymer, of ethylene derived; (ii) 2.0 to 4.0 wt %, based upon the total weight of the terpolymer, of 1-hexene derived units; and (iii) 93 to 97 wt %, based upon the total weight of the terpolymer, of propylene derived units, wherein the amount of 1-hexene derived units and the amount of ethylene derived units fulfils the following relationship (1): Tm>159−(C2+…
