Patent ID: 8722827

Claim:
A polyolefin composition comprising a cross-linkable polyolefin with: (A) hydrolysable silane groups which upon hydrolysation form an acid or a base, satisfying formula (I) as follows: R 1 SiR 2 R 3 R 4 (I); wherein R 1 is a non-hydrolysable hydrocarbyl group, which comprises 2 to 30 carbon atoms, and which further comprises at least one unsaturated group; and R 2 , R 3 and R 4 are organic residues; wherein at least one of R 2 , R 3 and R 4 generates an acid or a base upon hydrolysation; and (B) hydrolysable silane groups different from silane groups (A), satisfying formula (II) as follows: CH 2 ═CHSi(OA) 3 (II); wherein A is a hydrocarbyl group having 1-8 carbon atoms.
