Title:
ヘテロ相ポリプロピレンポリマー
Document Type and Number:
Japanese Patent JP6545703
Kind Code:
B2
Abstract:
A heterophasic propylene ethylene copolymer having an MFR 2 of 0.5 to 100 g/10min and obtained using single site catalysis comprising:
(i) a propylene homopolymer or propylene ethylene copolymer matrix having up to 4 wt% ethylene; and
(ii) an ethylene propylene rubber (EPR) dispersed in the matrix;
said heterophasic propylene ethylene copolymer having a xylene cold soluble content (XS) of 20 to 40 %;
wherein the ethylene content of the xylene cold soluble fraction of said heterophasic propylene ethylene copolymer is between 70 and 90 wt.%;
wherein the xylene cold soluble fraction of said heterophasic propylene ethylene copolymer has an intrinsic viscosity (IV) of 3.0 dl/g or more; and
wherein the melting enthalpy (Hm) of the heterophasic propylene ethylene copolymer is between 10 and 30 J/g at a temperature of 0 to 130°C.
