摘要:
The invention concerns a method for preparing high purity polyorganosiloxanes with arylalkyl function(s) by: hydrosilylation of a hydrogenopolyorganosiloxane, reagent (SiH), and an aromatic monovinyl compound, reagent (Vi), with simultaneous introduction of reagent (SiH) and reagent (Vi), in a reaction medium containing an inert solvent and a hydrosilylation catalyst; then elimination of the solvent, the possible residual reagents (SiH) and (Vi), and/or hydrogenation, the hydrogenation process being optionally followed by an elimination process (or another elimination process) of the products other than polyorganosiloxanes with arylalkyl function(s). The resulting silicones with arylalkyl function(s) can be used as emollients and/or carriers in cosmetic compositions, or as solubilizing agents and emollients in perfume compositions.

摘要:
A polychloroprene of sol type, the latices and solutions of which are gel free, exhibit improved rheological and other properties and are useful in the formulation of adhesive compositions, is readily prepared by polymerizing chloroprene in aqueous emulsion in the presence of X and Y chain transfer agents, said X chain transfer agent being present upon initiation of the polymerization and having a relative reaction velocity greater than that of chloroprene, and said Y chain transfer agent being incrementally or continuously added to the polymerization reaction medium over the course of the polymerization reaction and having a relative reaction velocity essentially the same as that of chloroprene.
摘要:
The invention relates to a double-layered compacted solid water-purification product, comprising at least one first layer and at least one second layer, characterized in that the first layer comprises at least one flocculating system and at least one dispersion system, the second layer comprises at least one disinfectant which liberates free chlorine on contact with water and at least one excipient for the disinfectant, whereby said excipient releases the disinfectant into the water at a controlled rate such that the combination of excipient and disinfectant releases 0.1 to 100 mg/l of free chlorine per hour. The invention further relates to the method for production of such a product.
