  • Hydrophobized cement-containing compositions
    Patent number: 7931747
    Abstract: The present invention relates to cement-containing compositions which are characterized in that they have a proportion of organosilicon compounds of greater than 0.15% by weight, based on the proportion of cement, the organosilicon compounds being based on at least one organosilicon compound selected from the group consisting of the alkoxysilanes and at least one selected from the group consisting of the alkoxysiloxanes, to a process for the preparation thereof and to the use thereof.

  • Use of organomodified siloxanes for surface modification of polyolefins
    Publication number: 20050032951
    Abstract: The invention provides for the use of organomodified polysiloxanes of the general formula (I) in which R1 independently at each occurrence is an aliphatic or aromatic C1-20 hydrocarbon radical, R2, R2* independently of one another are R1 or are aliphatic, saturated or unsaturated C1-60 hydrocarbon radicals, optionally containing functional groups, a=1 to 500, preferably <100, in particular 5 to 50, b=0 to 50, preferably <20, in particular <10, c=0 to 50, preferably 0 to 10, in particular 0 as additives for surface enhancement in polyolefins.
