<p>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 (R1)<sub>X</sub>[Si(R2)<sub>y</sub>(R<sup >3)<sub>z</sub>]<sub>m</sub> wherein R1, 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; R2, 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; R3, is -R4SiR1 <sub>P</sub>R2 <sub>q</sub>, wherein p is 0 to 3, q is 0 to 3, with the proviso that p + q is 3, and R4 is -(CH<sub>2</sub>)<sub>r</sub>Y<sub>s</sub>(CH<sub>2</sub>)<sub> t</sub>- 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<sub>2</sub>-, -NH-, -NR1- or -PR1-, where R1 and 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.</p> |
