Abstract: Block copolymers containing blocks of unsulfonated aromatic polyether sulfones and blocks of aromatic polyether sulfones sulfonated on the aromatics are characterized in that the block length of the unsulfonated aromatic polyether sulfones in each case comprises at least 10 repeating units and that the sequence of the main chain at the block transitions between two adjacent blocks of aromatic polyether sulfones is the same as it is inside these blocks. These block copolymers may be prepared by polycondensation, and are preferably used as membranes. The block copolymers provide compounds which in addition to an adjustable degree of sulfonation have a defined length of sulfonated and unsulfonated blocks. As a result, the spectrum of the polymers suitable for the preparation of synthetic membranes can be expanded and graded.

Abstract: A homogenous catalyst is prepared by reacting a ruthenium or molybdenum carbene catalyst of formula (I): in a non-reactive organic solvent or solvent mixture with a bicyclic olefin of formula (II): wherein X is O, NR1, C(R1)2, S, POR6, or PR6; R1 and R2 independently of each other, are H, (C1-C8)-alkyl, (C2-C8)-alkenyl, (C2-C8)-alkynyl, (C6-C18)-aryl, (C7-C19)-aralkyl, (C3-C18)-heteroaryl, (C4-C19)-heteroaralkyl, (C3-C8)-cycloalkyl, (C3-C8)-cycloalkenyl, (C6-C18)-aryl-(C1-C8)-alkyl, (C3-C18)-heteroaryl-(C1-C8)-alkyl, (C3-C8) -cycloalkyl-(C1-C8)-alkyl, or (C1-C8)-alkyl-(C3-C8)-cycloalkyl, or form together an ═O group; R3 and R4, independently of each other are OR1, SR1, NR12, OR7, SR7, or NR1R7 provided that at least one residue R3 or R4 bears a group R7, R6 is R1, provided that R6 is not H; R7 is a catalytically active group, and optionally with a further olefinic compound (III).

Abstract: A method for making antimicrobial, blood-compatible surfaces is provided, articles having surfaces made by this method, and the use of these articles in fields where controlling the spread of microbes and blood-compatibility are important. Such fields include the medical field, where it is critical to eliminate infection causing microbes and reduce the number of dangerous blood clots in patients.

Abstract: A hydrophilic coating on a polymeric substrate is prepared by subjecting at least one hydrophilic vinyl monomer to radiation-induced graft polymerization on an activated substrate surface.
