Field of the InventionThe invention relates to a phosphonic acid polymer, a production method thereof, and an electrolyte film for a fuel cell.2. Description of Related ArtPerfluorosulfonic acid-based polymers as represented by Nafion® are widely used as electrolyte films for polymer electrolyte fuel cells. However, since perfluorosulfonic acid-based polymers are extremely expensive, various proposals have been made regarding alternative materials thereto. One of these is a phosphonic acid polymer having phosphate groups introduced into a polymer side chain. An example of such a phosphonic acid polymer is disclosed in Japanese Patent Application Publication No. 2003-257238 (JP-A-2003-257238), and has phosphate groups introduced into the aromatic ring of polystyrene through methylene groups.However, the phosphonic acid polymer disclosed in JP-A-2003-257238 has an aromatic group having a large molecular weight in repeating units thereof. Consequently, the polymer dry weight (EW value) per mole of phosphate groups is relatively large, thereby resulting in the problem of decreased proton conductivity in comparison with phosphonic acid polymers of a structure that does not have an aromatic ring.This invention provides a phosphonic acid polymer having a high proton conductivity, a production method thereof, and an electrolyte film for a fuel cell.A first aspect of the invention is a phosphonic acid polymer containing a repeating unit represented by the following formula (1):(wherein, Rrepresents a hydrogen atom or methyl group).In addition, the electrolyte film ...

EFFECTIVE ANTIBACTERIAL HYDROPHILIC PHOSPHONIUM POLYMERS WITH LOW HEMOLYTIC ACTIVITY

Номер: US20210120822A1

This disclosure provides phosphonium polymers with increased hydrophilicity exhibiting increased antibacterial activity and decreased hemolytic activity. These phosphonium polymers include Poly(THPvbPCl) poly(tris(3-hydroxypropyl)(vinylbenzyl)phosphonium chloride) and derivatives thereof, ((2,3,4,6-Tetra-O-acetyl-manno-pyranyl)-1-oxy-allyl and derivatives thereof, and poly(dihexyl(2,3,4,6,-hydroxy-gluco-pyranyl)-1-oxy-propyl)vinylbenzylphosphonium chloride) and derivatives thereof. The present disclosure relates to phosphonium polymers with increased hydrophilicity exhibiting increased antibacterial activity and decreased hemolytic activity.Synthetic antibacterial polyelectrolytes containing ammonium or phosphonium functional groups have been widely investigated due to their increased activity as compared to their monomeric components. Many different nitrogen-containing polycations have been reported including polyammonium, polyimidazolium, polybiguanide, and polypyridinium salts. Antibacterial polymers have been synthesized as side chain ammonium functionalized synthetic linear polymers, dendrimers, and biopolymers such as chitosan. Along with the ionic groups, most active antibacterial polyelectrolytes possess alkyl chains that result in amphiphilic structures that have affinity for negatively charged bacterial cell walls. It is hypothesized that these units kill bacteria by damaging the cell membrane, causing permeabilization and leakage of cell contents, see reference.The balance of hydrophilicity-hydrophobicity for antibacterial polymers is one that has been explored by varying cationic:hydrophobic ratios. This can be completed by using copolymers with separate hydrophilic (cations) and hydrophobic (alkyl chain) components as shown in the molecule on left hand side of , or by having the hydrophilic and hydrophobic components within the same comonomer as illustrated by the molecule on the right hand side of . This seemingly subtle change can impart large ...

Hydrosilylation of polypropylene

Номер: WO1997047665A1
Принадлежит: UNIVERSITY OF WATERLOO

The hydrosilylation of terminal double bonds in polypropylene (PP) or other polymers is effected in the melt phase. The double bonds were created by peroxide initiated degradation of PP in an extruder or a batch mixer. A hydride terminated polydimethylsiloxane is employed as a model substance to investigate the feasibility of hydrosilylating the terminal double bonds of the degraded polypropylene. The reaction may be carried out in three different reactors, namely a hot press, a batch mixer and a screw extruder. Two different reaction mechanisms may be used to effect the hydrosilylation reaction, namely a radical chain addition mechanism and a platinum catalysed mechanism with a colloid forming catalyst, platinum divinyltetramethyldisiloxane (Karstedt's catalyst). Catalytic amounts of a peroxide initiator are able to initiate the addition of silanes to the double bonds of the degraded polypropylene. Both reactions, namely degradation and hydrosilylation, may be performed simultanously. A platinum colloid formed in the initial stage of the platinum catalysed hydrosilylation may be stabilized by adding t-butylhydroperoxide as cocatalyst, which results in the hydrosilylation at high yields.
