Abstract: The present invention relates to a catalyst masterbatch for cross-linking a polyolefin comprising cross-linkable silicon-containing groups comprising a Brønsted acid and/or Brønsted acid anhydride (A); and a polyolefin (B) containing Brønsted acid and/or Brønsted acid anhydride groups. The present invention further relates to a polyolefin composition comprising a polyolefin (C) comprising cross-linkable silicon-containing groups; a Brønsted acid and/or Brønsted acid anhydride; and a polyolefin (B) containing Brønsted acid and/or Brønsted acid anhydride groups. The present invention further relates to the use of the catalyst masterbatch according to the invention for cross-linking a polyolefin composition comprising a polyolefin with cross-linkable silicon-containing groups (C). The present invention further relates to the use of polyolefin (B) containing Brønsted acid and/or Brønsted acid anhydride groups together with a sulphonic acid silanol condensation catalyst in a polyolefin composition comprising: a polyolefin with cross-linkable silicon-containing groups (C). The present invention further relates to the use of the catalyst masterbatch according to any one of the preceding claims 1 to 11 in a cable layer.
