  • Patent number: 10227446
    Abstract: Described herein is a feasible, significantly simplified production method that avoids challenging lactonization steps and converts a low molecular weight aliphatic polyester, consisting of hydroxy acids and a comonomer, whose molecular weight has been increased by step-growth polymerization reactions. The molecular weight of the aliphatic polyester, based on comparison of initial and final weight average molecular weights (Mw,1/Mw,2), increased significantly at a rate which permits the use of reactive extrusion to produce high molecular weight aliphatic polyesters in a simple, economically feasible manner.

    Abstract: A method of developing degradable linear poly(ethylene glycol) PEG (DPEG) with multiple functioning capacities, which can be used as drug carriers for cancer cell delivery. A DPEG may be effective in targeting cancerous tumors through an enhanced permeation and retention effect (EPR). The DPEG will then degrade in the acidic extracellular fluid of solid tumors leading to fast cellular internalizations, finally degrading in the lysosome for efficient renal clearance. These may be used in conjunction with drugs and/or targeting groups. Furthermore, DPEGs are thermoresponsive, on an as needed basis, making them useful for in vivo application.

  • Patent number: 8026339
    Abstract: A polysulfone is provided with a nitrogen-containing functional group having an affinity to an acid, an electrolyte membrane using the polysulfone, and a fuel cell including the electrolyte membrane. In particular, the polysulfone includes a nitrogen-containing functional group that has an affinity to an acid, such as a phosphoric acid, thereby having an excellent acid retaining ability. In an electrolyte membrane including the polysulfone and an acid, the amount of the retained acid can be controlled. Therefore, the electrolyte membrane has a high ionic conductivity and a high mechanical strength. A polysulfone blend of polysulfone and a thermoplastic resin prevents the dissolution of polysulfone by phosphoric acid, so that an electrolyte membrane using the polysulfone blend has an improved durability. A cross-linked reaction product of polysulfone, a cross-linking agent and a polymerization product of polysulfone, a thermoplastic resin, and a cross-linking agent strongly resist a phosphoric acid.
