Abstract:
The invention is related to a new soft heterophasic random propylene copolymer with improved optical properties, as well as the process by which the heterophasic random propylene copolymer is produced.

Claim (Index 1):
A heterophasic propylene copolymer (RAHECO) having\n (a) a xylene cold soluble content (XCS) determined according ISO 16152 (25\u00b0 C.) in the range of 25.0 to 35.0 wt.-%, and (b) a comonomer content in the range of more than 4.5 to 10.0 wt.-%, wherein further (c) the comonomer content of xylene cold soluble (XCS) fraction of the propylene copolymer is in the range of 12.0 to 22.0 wt.-%, (d) the intrinsic viscosity (IV) determined according to DIN ISO 1628/1 (in decalin at 135\u00b0 C.) of the xylene cold soluble (XCS) fraction of the propylene copolymer is in the range of more than 1.5 to below 3.0 dl/g, and (e) the relative content of isolated to block ethylene sequences (I(E)) of the XCS fraction fulfilling the inequation (I)\n I(E)<78\u22121.97\u00d7C2+0.015\u00d7(C2) 2 \u2003\u2003(I) \n \u2003wherein C2 is the comonomer content [wt %] of the XCS fraction and \u2003wherein the I(E) content is defined by equation (II)\n I(E)= f PEP/(( f EEE+ f PEE+ f PEP))\u00d7100\u2003\u2003(II) \n \u2003wherein \u2003I(E) is the relative content of isolated to block ethylene sequences [in %]; \u2003fPEP is the mol fraction of propylene/ethylene/propylene sequences (PEP) in the sample; \u2003fPEE is the mol fraction of propylene/ethylene/ethylene sequences (PEE) and of ethylene/ethylene/propylene sequences (EEP) in the sample; \u2003fEEE is the mol fraction of ethylene/ethylene/ethylene sequences (EEE) in the sample \u2003wherein all sequence concentrations are based on a statistical triad analysis of 13C-NMR data.
