Abstract:
The present invention is directed towards random-heterophasic propylene copolymers with a specific ratio of stiffness to impact balance and specific relation between glass transition temperature and comonomer content. The invention is further directed to articles comprising said random-heterophasic propylene copolymer and their use.

Abstract:
Compatible heterogeneous polymer blends of polyethylene and polyamide, whereby the matrix of the blend comprises the polyethylene, which is a special linear low density polyethylene in native and/or recycled form, optionally in combination with a compatibilizer, whereby preferably the polyamide of the compatible heterogeneous blend is a postconsumer (i.e. recycled) polyamide, which can optionally contain at least one further polymer, like polyethylene.
Abstract:
Process for the production of polypropylene random copolymers containing 2.5 to 5.0 wt% of ethylene as comonomer and having an MFR 2 in accordance with ISO 1 133 (230°C, 2.16 kg load) of ≥ 25 g/10 min to 100 g/10 min and a hexane-solubles content, determined according to FDA CFR 21 § 177.1520 below 5 wt%, said process comprising the step of polymerizing propylene and ethylene in the presence of a catalyst system comprising (i) a Ziegler-Natta procatalyst which contains a trans-esterification product of a lower alcohol and a phthalic ester as internal donor and (ii) an organometallic cocatalyst and (iii) an external donor represented by formula (I) or (II) Si(OCH 2 CH 3 ) 3 (NR 1 R 2 ) (I) or Si(OCH 3 ) 2 (CH 3 )(cyclohexyl) (II) wherein R 1 and R 2 can be the same or different and represent a hydrocarbon group having 1 to 12 carbon atoms, the polypropylene random copolymers with a low level of odour and taste themselves and their use for injection moulding applications, preferably for thin-wall packaging for food packaging in non-cooking applications and for medical packaging.
Abstract:
The invention refers to a process for preparing a Group 2 metal/transition metal olefin polymerization catalyst component in particulate form having improved polymerization properties due to the use of H 2 during catalyst component preparation and the use of such catalyst components in a process for polymerizing olefins.
Abstract:
The present invention deals with a new unimodal propylene-ethylene random copolymer providing improved resistance against gamma irradiation as well as compositions comprising the new unimodal propylene-ethylene random copolymer and final articles made therefrom.
Abstract:
The invention relates to a polypropylene composition which combines low sealing initiation temperature (SIT) and high melting point (Tm), thus having a broad sealing window.
Abstract:
The present invention relates to a nucleated heterophasic polypropylene composition, which shows improved properties in view of mechanical and optical behaviour as well as low amounts of extractable. The present invention also relates to films and final articles made out of the heterophasic polypropylene composition, as well as their use in packaging, especially food packaging applications.
Abstract:
