PROPYLENE-ETHYLENE COPOLYMERS AND PROCESS FOR THEIR PREPARATION |
摘要 |
Random propylene/ethylene copolymers are provided characterized by Ethylene content in the range of 4.5-7%wt; Mw/Mn (via GPC) in the range 3. 5-5.5; Mz/Mw (via GPC) lower than 4; absence of 2-1 regioinversion, and Melting Temperature (Tm) (non-nucleated grade) lower than 143‹C. The said copolymers show an excellent balance of impact and optical properties which is retained even after visbreaking. ® KIPO & WIPO 2008
