Siloxane-containing oil compositions with good spreading properties

Phosphoric esters and their use as dispersants

The invention relates to phosphoric esters of the general formula (I):

The invention relates to polymethacrylate acid-polyalkylene oxide block copolymers, to a process for their preparation and to their use as dispersants or suspension stabilizers for pigments and fillers, e.g. for metal oxides in ceramic materials, for pigments in inks used in ink jet printing and for fillers in thermosplastic and thermoset polymers.

Mercapto-containing block copolymers having polymethacrylic acid and polyalkylene oxide repeating groups

The invention relates to block-polymethacrylate-block-polyalkylene oxide copolymers with terminal carboxylic acids, of the general formula I

Dispersants for preparing aqueous pigment pastes

Disclosed are polymethacrylic esters of the central formula ##STR1## in which the radicals R.sup.1 are identical or different and are alkyl radicals having 1 to 8 carbon atoms, perfluoroalkyl radicals or dialkylaminoalkyl radicals, and

Polymethacrylic esters whose ester groups in position and differ from

The invention relates to a process for preparing silanes or siloxanes having carboxyl functionalities, wherein a hydrogen silane or hydrogen siloxane compound is reacted with a tertiary butyl ester having an olefinic double bond and the sil(ox) ane-bonded tertiary butyl ester group is subsequently converted into the corresponding carboxyl group with elimination of isobutene.

Process for preparing carboxyl-functional silanes and siloxanes

Polyolefins, polyolefin blends and elastomer-modified polyolefins containing additives to increase the surface polarity are prepared. They contain AB block copolymers as additives. A method for preparation of polyolefins, polyolefin blends and elastomer-modified polyolefins with a polar surface is defined as well as the method of preparing the polyolefins articles.

Polyolefins, polyolefin blends and elastomer-modified polyolefins with

Inventive block copolymers are prepared, and their synthesis is described. These inventive block copolymers act as polymeric surfactants, especially as emulsifiers and surfactants, and as compounds having antistatic properties.
