PROPYLENE/1-HEXENE COPOLYMER COMPOSITION WITH BROAD SEALING WINDOW

摘要

Propylene copolymer composition (P) comprising (a) at least 2.5 wt.-% of units derivable from C5 to C12 a-olefins, (b) at least 20.0 wt-%. of a crystalline fraction having a lamella thickness of more than 5.70 nm, and (c) at least 10.0 wt-%. of a crystalline fraction having a lamella thickness of below than 3.0 nm, said crystalline fractions are determined by the stepwise isothermal segregation technique (SIST).
