Propylene-Ethylene Copolymers and Process for Their Preparation |
摘要 |
Propylene-ethylene copolymers are flexible and show a very good balance between softness and mechanical properties in their crude state are obtained by solution polymerization in the presence of Ziegler-Natta catalysts. The said copolymers comprise from 10 to 50% wt of ethylene and are characterized by: product of the comonomer reactivity ratio r1.r2<=1.5; absence of 2,1 propylene insertions and tensile strength at break higher than 4 Mpa.
