A proton conductive material comprising a proton-source-polymer and a proton-channel-polymer, wherein at least one selected from the group consisting of the proton-source-polymer and the proton-channel-polymer is a polymer containing an aromatic ring, and wherein at least a part of the polymer containing the aromatic ring has a stacked structure formed by n-n interactions, and a proton conductive material comprising a proton-source-crosslinked-polymer, wherein the proton-source-crosslinked-polymer is a polymer having a main skeleton which contains a proton source group and an aromatic ring, and a crosslinked structure which contains a proton channel, and wherein at least a part of the proton-source-crosslinked-polymer has a stacked structure formed by n-n interactions.

The present invention relates to a cross-linkable polyolefin composition comprising a first olefin polymer (A) comprising a first comonomer comprising epoxy groups, and a second olefin polymer (B) comprising a second comonomer comprising carboxylic acid groups and/or precursor thereof.

A thermoplastic elastomer composition includes the following components (I) and (II): [component (I)] at least one polymer component selected from the group made of particular polymers (A) and particular polymers (B); and [component (II)] a cross-linked styrene-based block copolymer which contains a covalent-bond cross-linking moiety and no hydrogen-bond cross-linkable moiety.

Pellet-stable olefinic copolymer bimodal rubber is made using parallel reactors, with one reactor synthesizing higher molecular weight (MW) rubber with dual catalysts, with an improved molecular weight split ratio and an improved composition distribution of the moderate and ultra-high MW components, while another reactor synthesizes random isotactic polypropylene copolymer (RCP). The effluents are reactor-blended and result in pellet-stable bimodal rubber (P-SBR), which may be pelletized. When making thermoplastic vulcanizates (TPVs) with P-SBR, the need to granulate rubber bales and subsequently use talc, clay, or other anti-agglomeration agents to prevent granulated rubber crumbs from agglomerating are eliminated. TPVs made with P-SBR have vulcanized rubber particles that are smaller and more uniform in size, resulting in TPVs with higher particle counts and more thermoplastic “ligaments” between the particles, with such ligaments being made stronger by the added RCP. Such thus-produced TPVs have a lower hysteresis and flexural modulus, and better elastic properties.

A polymer composition may include a polymer produced from ethylene, one or more branched vinyl ester monomers, optionally vinyl acetate (VA), and a thermoplastic polyurethane (TPU). A method of preparing a polymer composition may include blending a thermoplastic polyurethane (TPU) and an ethylene based polymer produced from ethylene, one or more branched vinyl ester monomers, and optionally vinyl acetate (VA); and to form a blended mixture; and extruding the blended mixture to form the polymer composition

The present invention relates to the treatment of ocular diseases in a human subject In particular, the invention relates to an intracameral administration of a sustained release biodegradable intracameral implant.

Co-cured blends of fluoroelastomers of tetrafluoroethylene-propylene copolymer with cure site monomer and terpolymers of Vinylidene fluoride (VDF), Hexafluoropropylene (HFP) and Tetrafluoroethylene (TFE) with peroxide as initiator and coagent TAIC as crosslinker show improved curing performance, improved mechanical properties and improved compression set as well. The co-cured fluoroelastomers show improved chemical resistance to the solvent aging systems and better retention of mechanical properties after aging at high temperature in the solvents system.

It becomes possible to produce a thermoplastic resin composition having a sea-island structure by a kneading step of kneading a thermoplastic elastomer and/or rubber material having an alkoxysilyl group, in which the alkoxysilyl group is grafted to the thermoplastic elastomer and/or rubber material, and a thermoplastic resin in a melt state in a kneading machine and a dynamic crosslinking step of adding a water component into the kneading machine, forming a silanol group by a hydrolysis reaction of the alkoxysilyl group in the thermoplastic elastomer and/or rubber material having an alkoxysilyl group and the water component in the kneading machine, and subsequently forming a siloxane bond by a condensation reaction between the silanol groups.
