The present disclosure provides copolymers useful in medical devices. For example, the disclosure provides copolymers comprising the polymerization product ester block, ether blocks and diisocyanates. In certain embodiments, the disclosure provides a medical copolymer for implantation comprising ester blocks and ether blocks, wherein: the ester blocks comprise a negative free energy transfer and the ether blocks comprise a positive free energy transfer, the ether and ester blocks are less than 1/10 the length of said copolymer, and, the blocks are distributed such that no domain of contiguous blocks possessing the same polarity of free energy transfer are less than ⅓ of the molecular weight of the copolymer. The disclosure further provides methods of making the aforementioned polymers, and medical devices comprising the polymers.

A crosslinkable composition containing: a liquid monocyclic olefin ring-opened polymer (A) having a reactive group at a polymer chain end thereof and a weight-average molecular weight (Mw) of 1,000 to 50,000; and a crosslinkable compound (B) having, in the molecule, two or more functional groups reactive with the reactive group at the polymer chain end of the monocyclic olefin ring-opened polymer (A).

An interpenetrating network (IPN) polymer membrane material includes a soft polyurethane interspersed with a crosslinked conducting polymer. The material can be reversibly “switched” between its oxidized and reduced states by the application of a small voltage, ˜1 to 4 volts, thus modulating its diffusivity.

The present application is directed to a nanocomposite organo gel having a continuous polymeric network structure, wherein polymer chains are held together by ionic interaction between polymer chain ends, interparticle chain entanglements, layered silicate surface modifier, ionic salt, and layered silicate. The present application is also directed to methods of making and using the nanocomposite organo gel.

Described herein are anionic phenylene oligomers and polymers, and devices including these materials. The oligomers and polymers can be prepared in a convenient and well-controlled manner, and can be used in cation exchange membranes. Also described is the controlled synthesis of anionic phenylene monomers and their use in synthesizing anionic oligomers and polymers, with precise control of the position and number of anionic groups.

The present invention is directed to nanofilaments for polymer brushes, to polymer brushes comprising the nanofilaments and methods of making the same. In particular, the invention provides water soluble nanofilaments which may be grafted to a surface and which may be functionalised with (bio)molecules.

Polyethylene glycol (PEG)-b-poly(β-amino ester) (PBAE) co-polymers (PEG-PBAE) and blends of PEG-PBAEs and PBAEs and their use for delivering drugs, genes, and other pharmaceutical or therapeutic agents safely and effectively to different sites in the body and to different cells, such as cancer cells, are disclosed.

Hydrocarbon proton exchange membranes are disclosed that are composed of a material including a hydrophobic main chain, and acidic side chains. The main chain includes a polyaryl structure that is substantially free of ether linkages and also includes a fluoromethyl substituted carbon. The acidic side chains include a hydrocarbon tether terminated by a strongly acidic group, such as a fluoroalkyl sulfonate group. Chemical stability of the material is increased by removing the ether linkages from the main chain. The hydrophobic main chain and substantially hydrophilic side chains create a phase-separated morphology that affords enhanced transport of protons and water across the membrane even at low relative humidity levels. These materials are advantageous as membranes for use in fuel cells, redox flow batteries, water hydrolysis systems, sensors, electrochemical hydrogen compressors, actuators, water purifiers, gas separators, etc.
