    摘要： A type of cationic dyeable polyester fiber and preparing method thereof are disclosed. The preparing method is to manufacture a fiber from a cationic modified polyester through a fully drawn yarn (FDY) process, wherein the cationic modified polyester is composed of terephthalic acid segments, ethylene glycol segments, sodium salt of diethylene ester of 5-sulfoisophthalic acid segments and tert-butyl branched diol segments and a molecular formula of tert-butyl branched diol is as following: The cationic modified polyester is further dispersed with a high temperature calcined solid heteropolyacid. A final fiber has a dye uptake of 87.8-92.2% and a K/S value of 23.27-25.67 when dyed at 120° C., as well as an intrinsic viscosity drop of 13-17% when stored at 25° C. and R.H. 65% for 60 months.

    摘要： Disclosed are compositions comprising polymeric nanoparticles and methods of using the same. The polymeric nanoparticles can be conjugated with a targeting ligand that is a substrate for a solid tumor-specific cell protein. The polymeric nanoparticles can also comprises an imaging compound and/or a therapeutic agent encapsulated in the hydrophobic interior of the nanoparticle. A cancer therapeutic composition comprising the nanoparticle is also disclosed. The disclosed nanoparticles can be used to target and deliver imaging and/or therapeutic compounds to cancer cells, thereby identifying and/or treating a solid tumor cell target. Methods for treating cancer, such as lung cancer, using the polymeric nanoparticles are also disclosed.

    摘要： The composite particles contained in an inkjet ink are particles of a composite of a polyester resin having a sulfur atom-containing polar group and a dye. The polyester resin is non-crystalline. The polyester resin has a first repeating unit derived from a polyvalent carboxylic acid having the sulfur atom-containing polar group, a second repeating unit derived from a polyvalent carboxylic acid having no sulfur atom-containing polar group, and a third repeating unit derived from a polyhydric alcohol. The content percentage of the first repeating unit relative to a total amount of the first repeating unit and the second repeating unit is 1 to 10 mol %. The content percentage of the polyester resin relative to the composite particles is 50% by mass or more and less than 100% by mass.

    摘要： Polyester polyols, processes for making them, and applications for the polyols are disclosed. Some of the polyols comprise recurring units from a digested thermoplastic polyester (e.g., recycled polyethylene terephthalate), a diol, an optional hydrophobe, and a clarifier. The clarifier, which in some cases is a bisphenol, bisphenol alkoxylate, bisphenol polycarbonate, sulfonyl diphenol, or sulfonyl diphenol alkoxylate, helps the polyol remain clear for weeks or months after its preparation. In some aspects, the clarifier is a monophenol, bisphenol, or poly-phenol having two or more phenylene rings wherein at least two of the phenylene rings lack a common molecular axis. The clarifier may also be an alkylated phenol, an epoxy resin, an epoxy novolac resin, a diphenylmethane, or a tris(aryloxy)phosphate. The polyols are valuable for formulating a variety of polyurethanes and related products—including polyurethane dispersions, flexible and rigid foams, coatings, adhesives, sealants, and elastomers—and they provide a sustainable alternative to bio- or petrochemical-based polyols.

    摘要： Described are shape-memory polymers that have a composite prepolymer crosslinked with a stoichiometric amount of a multifunctional crosslinker, the composite prepolymer having a branched or telechelic prepolymer having a low polydispersity reacted with a non-crystalline chain extender. Also described are methods of making shape-memory polymers by reacting a branched or telechelic prepolymer having a low polydispersity with a non-crystalline chain extender to form a composite prepolymer, and crosslinking a stoichiometric amount of a multifunctional crosslinker with the composite prepolymer, thereby forming the shape-memory polymer.
