20140323685CROSS-LINKED POLYZWITTERION/ANION FOR THE REMOVAL OF STRONTIUM FROM AQUEOUS SOLUTIONS - The cross-linked polyzwitterion/anion for the removal of strontium from aqueous solutions is a polyzwitterion having the following structure:10-30-2014
20140275469AMINE FUNCTIONAL POLYAMIDES - Amine functional polyamides comprise amine and ammonium groups along the polymer chain. Amine functional polyamides can be used as pharmaceutical agents and in pharmaceutical compositions. The amine functional polyamides are particularly useful in the treatment or prevention of mucositis and infection, specifically oral mucositis, surgical site infection, and lung infection associated with cystic fibrosis.09-18-2014
20090318662Hydrazine storage resin - A hydrazine-fixing group such as a ketone group, a formyl group, a chlormethyl group or an amide group, which is capable of releasably fixing hydrazine, is introduced into a side chain of a synthetic resin, and hydrazine is fixed to the hydrazine-fixing group. Since a hydrazine storage resin of the present invention has a hydrazine-releasable group capable of releasing hydrazine, it is able to store hydrazine stably. In addition, hydrazine can be supplied by releasing hydrazine from the hydrazine-releasable group. Consequently, the hydrazine storage resin can be widely used in various industrial fields requiring supply of hydrazine.12-24-2009
20100292432POLYMERS FOR POLYNUCLEOTIDE ENCAPSULATION - The present invention provides block copolymers comprising hydrophobic moieties in a cationic complexing block, methods of preparing the same, and intermediates thereto. The compounds are useful in a variety of applications such as the assembly of micellar polyion complexes. The invention further provides methods of using said compounds and compositions thereof.11-18-2010
20100168374Diamine compound having dendron side chain and liquid crystal aligning agent using same - Disclosed herein is a novel functional diamine compound having a dendron structure, polyamic acid which is produced using functional diamine, aromatic cyclic diamine, aliphatic cyclic acid dianhydride, and aromatic cyclic acid dianhydride, polyimide which is produced by imidizing polyamic acid, and an LC alignment film produced using polyimide. Even if the diamine compound is used in a small amount, it is possible to realize a high pretilt angle, thus the pretilt angle is easily controlled. Therefore, it can be used to produce an LC alignment film using a twisted nematic (TN) mode, in which the pretilt angle of liquid crystal is low, and a vertically aligned (VA) mode, which requires a high pretilt angle of about 90°.07-01-2010
