Patent
Borealis | Date: 2017-05-17

The present invention relates to a heterophasic polypropylene composition with rather high melt flow rate, high stiffness, good impact properties and an advantageous balance between stiffness and impact behaviour, as well as articles made thereof.


Patent
Borealis | Date: 2017-02-08

Heterophasic propylene copolymer comprising a propylene - C4 to C12 a-olefin copolymer a matrix in which an ethylene-propylene rubber is dispersed, said heterophasic propylene copolymer has good mechanical properties and low extractables.


Heterophasic propylene copolymer for retortability, said copolymer has a comonomer content in the range of 1.5 to 14.0 mol-%; a melting temperature in the range of 140 to 15C and a xylene cold soluble (XCS) fraction in the range of 10.0 to below 30.0 wt.-%.


The present invention is directed to a heterophasic propylene copolymer (HECO), a polyolefin composition (PO) comprising the heterophasic propylene copolymer (HECO), an automotive article comprising the heterophasic propylene copolymer (HECO) and/or the polyolefin composition (PO) and a process for the preparation of the polyolefin composition (PO) as well as the use of the heterophasic propylene copolymer (HECO) for improving the mechanical properties of a polyolefin composition (PO).


The present invention is directed to a layer of an electrical device a photovoltaic module comprising at least one photovoltaic element and at least one layer comprising a polypropylene composition and to the use of a polypropylene composition for producing at least one layer of an element of a photovoltaic module.


Catalyst system for producing ethylene copolymers in a high temperature solution process, the catalyst system comprising (i) a metallocene complex of formula (I) wherein M is Hf or Zr X is a sigma ligand, L is a bridge of the formula -SiR82-, wherein each R8 is independently a C1-C20-hydrocarbyl, tri(C1-C20-alkyl)silyl, C6-C20-aryl, C7-C20-arylalkyl or C7-C20-alkylaryl n is 0, 1 or 2 R1 and R1 are the same or can be different and can be a linear or branched C1-C6-alkyl group, R2 and R2 are the same or are different and are a CH2-R9 group, with R9 being H or linear or branched C1-C6-alkyl group R5 and R5 are the same or are different and can be H or a linear or branched C1-C6-alkyl group or a OR group, wherein R is a C1-C6-alkyl group R6 and R6 are the same or are different and can be H or a C(R10)3 group, with R10 being the same or different and R10 can be H or a linear or branched C1-C6-alkyl group or R5 and R6 and/or R5 and R6 taken together form an unsubstituted 4-7 membered ring condensed to the benzene ring of the indenyl moiety, with the proviso that if R5 and R6 as well as R5 and R6 taken together form an unsubstituted 5 membered ring condensed to the benzene ring of the indenyl moiety then R2 and R2 are not a C1-alkyl group; and R7 and R7 can be the same or are different and can be H or a linear or branched C1-C6-alkyl group (ii) an aluminoxane cocatalyst and (iii) optionally a boron containing cocatalyst
