Abstract
The invention relates to a polymer composition comprising a polyethylene and a crosslinking agent, wherein the polymer composition contains a total amount of vinyl groups which is B vinyl groups per 1000 carbon atoms, and B1≤B, wherein B1 is 0.88, when measured prior to crosslinking according to method ASTM D624898; and wherein the crosslinking agent is present in an amount which Z wt %, based on the total amount (100 wt %) of the polymer composition, and Z≤Z2, wherein Z2 is 0.60, an article being e.g. a cable, e.g. a power cable, and processes for producing a polymer composition and an article; useful in different end applications, such as wire and cable (W&C) applications.

A polymer composition comprising a polyethylene and a crosslinking agent, wherein:
- the polymer composition contains a total amount of vinyl groups which is B vinyl groups per 1000 carbon atoms, and B≥0.88, when measured prior to crosslinking according to method ASTM D6248-98;
- the crosslinking agent is present in an amount which is Z wt %, based on a total amount (100 wt %) of the polymer composition, and Z≤0.60;
- and
- the polymer composition has, prior to crosslinking, a melt flow rate at 2.16 kg loading (MFR2) and at 190° C., determined according to method ISO 1133-1:201, wherein the MFR2 is A g/10 min and A≤2.5, and
- the polyethylene is a low density polyethylene (LDPE) homopolymer or copolymer.
