Abstract
The present invention relates to a catalyst masterbatch for cross-linking a polyolefin having cross-linkable silicon-containing groups. The catalyst masterbatch includes both of a Brønsted acid and/or Brønsted acid anhydride (A); and a polyolefin (B) containing Brønsted acid and/or Brønsted acid anhydride groups. The invention also encompasses compositions of a polyolefin having cross-linkable silicon-containing groups that include the catalyst masterbatch, use of the catalyst masterbatch in a cross-linking reaction of silicon-containing polyolefins, and a cable layer that includes a polymer made using the catalyst masterbatch.
Claims11
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 anhydride groups,
- wherein the Brønsted acid and/or Brønsted acid anhydride (A) are selected from carboxylic acids, carboxylic acid anhydrides, sulphonic acid and/or sulphonic acid anhydrides;
- wherein (A) is present in an amount of from 0.5 to 20 wt %, and
- wherein (B) is present in an amount of from 15 to 99 wt % based on the total weight of the catalyst masterbatch.
