    • The present invention relates to a composition comprising (i) a crosslinkable polyolefin with hydrolysable silane groups (A), (ii) a silanol condensation catalyst (B), and (iii) a silicon containing compound (C) according to the formula (R 1 ) x [Si(R 2 ) y R 3 ) z ] m (I) wherein R 1 , which may be the same or different if more than one such group is present, is a monofunctional, or, if m = 2, is a bifunctional, hydrocarbyl residue comprising from 1 to 100 carbon atoms and at least one heteroatom; R 2 , which may be the same or different if more than one such group is present, is a hydrocarbyloxy residue comprising from 1 to 100 carbon atoms; R 3 , is -R 4 SiR 1 p R 2 q , wherein p is 0 to 3, q is 0 to 3, with the proviso that p + q is 3, and R 4 is -(CH 2 ) r Y s (CH 2 ) t - where r and t independently are 1 to 3, s is 0 or 1 and Y is a difunctional heteroatomic group selected from -O-, -O-(CO)-, -NH-, -NH 2 , -NH-(CO)-NH 2 , -NH-(CO)-OCH 3 , an epoxy group, a carbamate group, -S-, -SO-, -SO 2 -, -NR-, -PR-, where R is a hydrocarbon or a hydrogen and where R 1 and R 2 are as previously defined; and x is 0 to 3, y is 1 to 4, z is 0 or 1, with the proviso that x + y + z = 4; and m = 1 or 2; to an article, in particular a wire or cable, comprising such a composition, and to the use of such a composition for the production of an article. The present invention further relates to the use of silicon containing compound (C) according to the formula (I) given above as a processing aid in the compounding of polyolefin compositions and as a surface smoothening agent in polyolefin compositions. Finally, the present invention relates to the use of a silicon containing compound (C) according to the formula (I) given above as a drying agent for polyolefin compositions, as a corrosion inhibitor in polyolefin compositions comprising a Brönsted acid and as a pH controlling agent in polymer compositions comprising a Brönsted acid.
