Additive masterbatch with a C3-C5 alpha-olefin homo- or copolymer comprised in the carrier

摘要

The present invention relates to a polyethylene composition comprising:
a) a polyethylene having cross-linkable silicon-containing groups (A); and
b) a masterbatch comprising
- one or more additives; and
- a carrier comprising a C 3 -C 5 alpha-olefin homo or copolymer (B).
The present invention further relates to a cross-linked polyethylene composition obtainable by treating the composition according to any one of the preceding claims under cross-linking conditions. The present invention also relates to the following uses:
Use of a masterbatch comprising
- an additive; and
- a carrier comprising a C 3 -C 5 alpha-olefin homo- or copolymer (B) for adding an additive to a polyethylene with cross-linkable silicon-containing groups.
Use of C 3 -C 5 alpha-olefin homo- or copolymer (B)as carrier for additive(s) to improve the performance of a silanol condensation catalyst when cross-linking a polyethylene composition further comprising
- a polyethylene with cross-linkable silicon-containing groups.
