MODIFIED SULPHUR
The invention provides modified sulphur comprising sulphur and a polysulphide-containing organosilane in an amount of in the range of from 0.3 to 25 wt % based on the weight of sulphur, in which modified sulphur the combined amount of sulphur and polysulphide-containing organosilane make up in the range of from 90 to 100 wt % of the obtained modified sulphur and wherein the polysulphide-containing organosilane is of the general molecular formula (1): (X3Si)mH(2n+1−m)Cn-Sa-Cn′H(2n′+1−m′)(SiX′3)m′; wherein a is an integer in the range of from 2 to 8, X and X′ each are, independently, a hydrolysable group, n and n′ each are, independently, an integer in the range of from 1 to 4, and m and m′ each are, independently, an integer in the range of from 1 to (2n+1). The invention further provides a process for preparing such modified sulphur, a sulphur cement product comprising the modified sulphur and a process for preparing such.
