The invention relates to new oil gelling polyurethanes useful for preparing clear gels in organic media (oils, solvents) and to a process for their preparation. The invention also relates to the gels formed from these gelling polyurethanes and to compositions containing them, in particular cosmetic compositions.

Polyurethane gelling agent

The invention relates to an aqueous viscoelastic solution comprising: at least one polymer selected from among hyaluronic acid and the salts thereof, and cellulosic derivatives and the salts thereof, in particular hydroxypropyl methylcellulose and the salts thereof; and at least one water-soluble polymer of the polyether-polyurethane or polyether-polyester-urethane type, and to the use thereof in a device intended for the injection of an intraocular implant.

The invention relates to a process for preparing cements used for reparative or reconstructive bone surgery, in particular for fixing prostheses, for bone repair and for vertebroplasty, and obtained from liquid single-phase formulations. It also relates to the cements prepared from these single-phase formulations and to a device for injecting them.

The invention relates to a sizing composition intended to be applied to mineral fibers, especially glass or rock fibers, which contains at least one polycarboxylic acid and at least one polyamine. It also relates to a method of preparing the composition, to its use for sizing mineral fibers for the purpose of forming, in particular, thermal and/or acoustic insulation products, and to the products obtained.

The invention concerns an implant forming an intraocular lens comprising a central optical part, a globally circular outline, at least partly made of a flexible material and a haptic part, at said optical part periphery, made at least partially of a rigid material. Said implant has a single-piece structure. The implant rigid material is a shape modified by at least one process selected among chemical reactions and polymerisation reactions of the starting flexible material, for example based on PMMA-PHMA, cross-linked by adding a multifunctional agent such as diethyleneglycol dimethacrylate.

Bimaterial intraocular implant and process for making the implant

Polymers which comprise polymer chains of terpolymer type which are constituted by poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) of PEO-PPO-PEO form, which are modified at their termini by groups which can essentially be other chains of PEO-PPO-PEO, acid segments, amine groups or PEOs, these chains being linked to the terpolymer chains via chemical bridges which are constituted by urethane bridges, urea bridges, allophanate bridges and biuret bridges, and which comprise more than 80% by weight of said PEO-PPO-PEO. Thermoreversible physical gels of high viscosification index, which contain these polymers, and their uses. Preparation of these polymers and of these gels.
