The present invention relates to polymers comprising one or more perfluoroalkylpolyether units and one or more different charged units, to a process for producing such polymers in non-porous or particularly in porous form and to mouldings composed thereof. The novel polymers have an improved wettability and cell growth ability and are thus useful, for example, for the manufacture of biomedical devices, in particular opthalmic devices.
The invention provides a polymer comprising a chain of detectable units joined together by linker arms. The detectable units may be, for example, antigenic or form part of a fluorescent or chemiluminescent or chromogenic or enzyme signal system. The polymer may find an application in the assay of an analyte which is a member of a specific binding pair. The invention also provides a labelled reagent in which the reagent is a member of a specific binding pair and the label is a polymer in accordan...
Stabilized polymers and copolymers of saturated cyclic ethers, such as epoxypropane, are obtained by contacting the ether with a catalyst obtained by reacting a trivalent metal compound with a divalent metal compound, such as an organo-aluminum-zinc compound, and stopping the reaction by adding an amine or amide to the reaction system. Aniline is a particularly preferred polymerization stopper. The catalytic residue must be left in the polymerizate.

The present invention provides polymeric and pharmaceutical compositions comprising a polymer that contains vicinal amine moieties, referred to as polyvicinalamine polymers. The polyvicinalamines can be copolymers or homopolymers. Methods of use of the polymeric and pharmaceutical compositions for therapeutic and/or prophylactic benefits are disclosed herein. Examples of these methods include the treatment of renal diseases, hyperphosphatemia, and the removal of bile acids, oxalates and iron fro...
Provided are novel polymerizable monomers allowing preparation of exceptionally useful surface coatings by polymerization. Embodiments include highly reticulated chiral nanoparticles useful, for example, for covalently grating biological ligands, epitaxial growth of conductive polymers onto surface modified indium tin oxide (ITO) electrodes and arrays of gold nanodots and electroconductive polymers.
A monomer which luminesces in the visible region upon excitation is described of the formula: M.sup.n+ (L).sup.n- (CL).sub.x in which n+ is the valency of M, (L) represents one or more anionic ligands with a total valency of n such that at least one of the ligands possesses the formula: Ch-X--Y wherein Ch represents a chelating group which is a ligand fragment comprising the chelate binding sites and the part of the rest of the ligand with which the binding sites are conjugated, Y represents an ...
