Aqueous 1-component silicone composition

The invention relates to particles comprises of organopolysiloxane microgel particles having a diameter of 5 to 200 nm and organo-aluminum compounds immobilized thereon. The particles can be used as cocatalysts together with metal compounds of the 4, 5, 6 and 8-10 sub-groups of the periodic table for oligomerization, cyclization of polymerization of olefins.

Organo-aluminum compounds immobilized on organopolysiloxane microgel particles

A continuous process for the polymer-analogous reaction of polymers bearing functional groups with reactive compounds, wherein in a first step, a mixture is prepared from the polymers bearing functional groups and the reactive compounds, and in a second step, the mixture is conducted continuously through a reaction zone and brought to reaction there.

Organopolysiloxanes with dye residues

Organopolysiloxane particles consist of a single molecule, are crosslinked, and contain metal atoms in the zero valent oxidation state, the metal atoms in each case being in intermetallic interaction with at least one further metal atom in the zero valent oxidation state, have an average diameter of 5 to 200 nm and are soluble to the extent of at least 0.1% by weight in at least one organic solvent chosen from the group consisting of methylene chloride, pentane, acetone, toluene and ethanol, at least 80% of the particles having a diameter which deviates from the average diameter by not more than 30%.

The organopolysiloxane particles consist of a single molecule, are crosslinked and have an average diameter of 5 to 200 nm. At least 80% of the particles have a diameter which deviates from the average diameter by not more than 30%. The particles are soluble in a solvent to the extent of at least 5% by weight.
