The invention provides a polyolefin composition comprising (i) a polyolefin (A) comprising epoxy groups; and (ii) a polyolefin (B) comprising carboxylic acid groups and/or precursors thereof, with the proviso that at least one of (A) and (B) is polyethylene. Preferably one of (A) and (B) is a low density polyethylene (LDPE) and the other is a polypropylene.

Polymer compositions comprising mixtures of polyolefins

A polymer composition comprising: (i) at least 40 wt % LDPE; (ii) a polypropylene homopolymer; and (iii) a random heterophasic polypropylene copolymer.

Polymer composition for cable insulation

The present invention relates to an ethylene polymer composition comprising: (A) an ethylene polymer comprising epoxy-groups, and (B) a cross-linking agent comprising: (B1) an organo-metallic Lewis acid, and at least one of: (B2) a compound comprising at least one amino group; and (B3) a compound comprising at least one hydroxyl group.

Cross-linkable ethylene polymer composition comprising epoxy-groups and a cross-linking agent

The present invention relates to a cross-linkable polyolefin composition comprising a first olefin polymer (A) comprising a first comonomer comprising epoxy groups, and a second olefin polymer (B) comprising a second comonomer comprising carboxylic acid groups and/or precursor thereof.

Cross-linkable polyolefin composition comprising a first and a second olefin polymer

The invention provides a polymer composition comprising a) a low density polyethylene (LDPE); and b) a conjugated aromatic polymer. The invention also relates to cables comprising said polymer composition and the use of the polymer composition in the manufacture of an insulation layer of cable.
