The present invention relates to the use of a silicon containing compound as corrosion inhibitor in polyolefin compositions, wherein the silicon containing compound has a structure according to the formula (R1) x [Si (R2) y(R3)z]m 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 hydro carbyloxy residue comprising from 1 to 100 carbon atoms; R3, is-R4SiR1pR2q, wherein p is 0 to 3, q is 0 to 3, with the proviso that p + q is 3, and R4is-(CH2)rYs(CH2)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-,-S-,-SO-,-SO2-,-NH-,-NR1-or-PR1-, where R1and R2are 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.
