The present invention relates to novel co-polymers and their use in the manufacture of porous membranes for haemodialysis application. In particular, such a co-polymer comprises a first segment comprising recurring units poly(aryl ether sulfone) [PAES recurring units], and a second segment comprising-recurring units poly(vinyl pyrrolidone) [PVP recurring units], wherein said first segment and said second segment are linked together via a group of formula —O-Ph-NH—C(═O)—C(CH)—CH—.

Membrane and polymer for the manufacture thereof

The present invention pertains to an aqueous dispersion of a vinylidene fluoride polymer having a high molecular weight and possessing a substantially linear structure, leading to reduced amount of gels/insoluble fractions, to a method for its preparation and to its use for the manufacture of electrochemical cell components, such as electrodes and/or composite separators or for the manufacture of membranes.

Vinylidene fluoride polymer dispersion

The present invention relates to medical devices, such as catheters, made from a composition comprising at least one (per) fluoropolyether polymer; methods for the manufacture thereof; and their uses and applications in medicine.

Medical devices

The present invention relates to a porous membrane, process for the manufacture thereof and uses thereof.

Porous membranes

The present invention relates to a composition comprising at least one aromatic polymer and at least one fluorinated polymer, articles made from such compositions and uses thereof.

Composition comprising aromatic and fluorinated polymers and use thereof

The present invention pertains to a process for the manufacture of a grafted fluoropolymer [polymer (Fg)], said process comprising reacting: A) at least one fluoropolymer comprising at least one functional group selected from the group consisting of a hydroxyl group and a carboxylic acid group [polymer (F)], B) at least one polyoxyalkylene (POA) of formula (I): R&#x2014;(CH&#x2014;O)&#x2014;(CHCHRO)&#x2014;(CH&#x2014;O)&#x2014;R, wherein at least one of Rand Ris a reactive group comprising at least one heteroatom selected from oxygen and nitrogen different from the hydroxyl group, the remaining, if any, being a &#x2014;[O]&#x2014;CHalkyl group, wherein z is 0 or 1, Ris a hydrogen atom or a C-Calkyl group, x and x', equal to or different from each other, are independently 0 or 1, and n is an integer comprised between 2 and 1000, preferably between 5 and 200, C) optionally, in the presence of at least one catalyst, and D) optionally, in the presence of at least one organic solvent (S). The present invention also pertains to grafted fluoropolymers obtained from said process and to uses of said grafted fluoropolymers for manufacturing porous membranes.
