摘要

Use of a silicon containing compound as a corrosion inhibitor in a polyolefin composition comprising a brönsted acid The present invention relates to the use of a silicon containing compound as a corrosion inhibitor in polyolefin compositions wherein the silicon containing compound has a structure according to the formula: (r ^ 1 ^) x [si (r ^ 2 ^) y (r ^ 3 ^) z] m in which: r ^ 1 ^ which may be the same or different if one more of these group is present is a monofunctional, or, if m = 2, bifunctional hydrocarbyl residue comprising from 1 to 100 carbon atoms; R 2, which may be the same or different, if one more of this 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 ~, where: p is 0 to 3, q is 0 to 3, provided that p + q is 3 ; er ^ 4 ^ (ch ~ 2 ~) ~ r ~ y ~ s ~ (ch ~ 2 ~) ~ t ~ -, where ret are independently 1 to 3, s is 0 or 1 and y is a bifunctional heteroatomic group selected from -0-, -s-, -so-, -s0 ~ 2 ~ -, -nh-, -nr ^ 1 ^ - or -pr ^ 1 ^ -, where r ^ 1 ^ and r ^ 2 ^ are as previously defined; and x is a 3, y is 1 to 4, z is o or 1, with the proviso that x + y + z = 4; and m = 1 or 2.
