The present invention relates to the use of a silicon containing compound as drying agent of a polyolefln composition comprising a crosslinkable polyolefin with hydrolysable silane groups, wherein the silicon containing compound has a structure according to the formula (R)[Si(R)(R)](I), wherein R, which may be the same or different if more than one Rgroup is present, an alkyl, arylalkyl, alkylaryl or aryl group containing 1 to 40 carbon atoms, with the proviso that if more than one Rgroup is present the total number of carbon atoms of the Rgroups is at most 60; and R, which may be the same or different if more than one such group is present, is an alkoxy, aryloxy, alkylaryloxy, or arylalkyloxy group containing 1 to 15 carbon atoms, with the proviso that if more than one Rgroup is present the total number of carbon atoms in the alkyl moieties of the Rgroups is at most 40; Ris -RSiRR, wherein p is 0 to 3, q is 0 to 3, with the proviso that p + q is 3, and Ris -(CH)Y(CH)- where r and t independently are 1 to 3, s is 0 or 1 and Y is a difunctional heteroatomic group selected from -O-, -S-, -SO-, -SO-, -NH-, -NR- or –PR-, where Rand R2 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. |
