The present invention relates to the use of a silicon containing compound for reducing the retention time of a polyolefin composition comprising a crosslinkable polyolefin with hydrolysable silane groups. A master batch is compounded with the polyolefin composition to form a compounding composition.
The present invention relates to the use of a silicon containing compound for reducing the retention time of a polyolefin composition comprising a crosslinkable polyolefin with hydrolysable silane groups. A master batch is compounded with the polyolefin composition to form a compounding composition. The master batch comprises a matrix polymer, a Bronsted acid that is a silanol condensation catalyst and is present in the amount of 0.7 to 3.5 wt %, and a silicon containing compound with a structure according to the formula (I): (R1)xSi(R2)y(R3)zm wherein R1 is C6-22 alkyl, R2 is C1-10 alkoxy, R3 is —R4SiR1R2 , R4 is —(CH2)rYs(CH2)t— where Y is a difunctional heteroatomic group, x+y+z=4, and m=1. The silicon containing compound is 2 to 10 wt % of the master batch, and 0.01 to 1.5 wt % of the compounding composition.
