PROPYLENE BASED TERPOLYMERS

摘要

A propylene-based terpolymer comprising: a) from 10.0% by mol to 79.0% by mol of propylene derived units; b) from 89.5% by mol to 20.5% by mol of 1 -butene derived units; and c) from 0.5% by mol to 15% by mol of derived units of alpha olefin of formula CH₂=CHZ wherein Z is a C₄-C₂₀ alkyl radical.
