Abstract:
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): wherein C6 is the amount of 1-hexene derived units in wt %, C2 is the amount of ethylene derived units in wt %, and Tm is the melting point of the terpolymer, wherein the terpolymer has a polydispersity index (PI) ranging from 2.0 to 7.0, and a melt flow rate from 2 to 20 g/10 min, as measured at 230 ° C. and 2.16 kg.
