Abstract: The invention consists of formulations based on compounds of platinum encapsulated by associative and water-soluble polymers. These formulations are in aqueous form or in the form of granulates. The invention further pertains to pharmaceutical preparations which contain these formulations, and their implementation in the fabrication of an orally administered medication, in polychemotherapy treatments.

Abstract: The invention pertains to improving the workability of an aqueous formulation with a hydraulic binder base using a combination between at least one comb-branched copolymer having a (meth)acrylic skeleton, onto which are grafted side-chains terminated by a hydrophilic group, and at least one comb-branched copolymer having a (meth)acrylic skeleton, onto which are grafted side-chains terminated by a hydrophobic group.

Abstract: The invention relates to the technical field of mortars, concretes, and other compositions based on cement, and in particular to agents capable of modifying their rheological characteristics, in particular workability. Workability may be defined as the property of a hydraulic binder to remain workable during as long a time as possible. The invention relates to novel agents of the acrylic copolymer type having urethane functions for improving the workability of hydraulic binders, to a method of preparing such novel agents, to binders containing them, and to uses for them. Such agents have the advantageous property of not retarding the setting time.
