  • Patent number: 8822579
    Abstract: A rubber compound based on propylene-oxide rubber SKPO, including sulfur, stearic acid, zinc oxide, thiuram disulphide, carbon black P-803. The compound is characterized by replacement of 2-mercaptobenzothiazole (kaptax), as well as fluoroplastic F-4, with dibenzothiazyl disulfide (altax), phenyl-?-naphthylamine (neozone D), dibutoxyethyl adipate, and natural bentonites. Use of a rubber compound with the proposed composition increases the service life of rubber seals during their operation in sealing devices, due to higher frost resistance and a lower residual compressive strain value. Also, the compound can be manufactured by a simpler method compared to modern production technology, eliminating the stage of joint mechanical activation of zeolite and dibutyl phthalate.

  • Patent number: 8816003
    Abstract: This invention involves a composition, a method of making, and an application of high plasticization-resistant chemically cross-linked polymeric membranes such as cross-linked cellulose acetate (CA) membrane. These cross-linked polymeric membranes with covalently interpolymer-chain-connected rigid networks showed no decrease in CO2/CH4 ideal selectivity under 690 kPa (100 psig) pure CO2 pressure and also no CO2 plasticization up to 3447 kPa (500 psig) pure CO2 pressure. By using the method of chemical cross-linking as described in this invention, the separation characteristics of the polymeric membranes can be decisively improved. These new cross-linked polymeric membranes can be used not only for gas separations such as CO2/CH4 and CO2/N2 separations, O2/N2 separation, olefin/paraffin separations (e.g. propylene/propane separation), iso/normal paraffins separations, but also for liquid separations such as pervaporation and desalination.

  • Patent number: 8691919
    Abstract: A simple procedure is provided by which the hydroxyl termini of poly(ethylene oxide) can be appended with functional groups to a useful extent by reaction and precipitation. The polymer is dissolved in warmed toluene, treated with an excess of organic base and somewhat less of an excess of a reactive acylating reagent, reacted for several hours, then precipitated in isopropanol so that the product can be isolated as a solid, and salt byproducts are washed away. This procedure enables functionalization of the polymer while not requiring laborious purification steps such as solvent-solvent extraction or dialysis to remove undesirable side products.

  • Patent number: 8604127
    Abstract: The present invention relates to a conjugate of a protein or peptide with a polyethylene glycol derivative having catechol, wherein the protein or peptide is mono-PEGylated at the N-terminal with the polyethylene glycol derivative, and to a preparation method thereof. According to the invention, the catechol-PEG derivative can be site-specifically conjugated with the N-terminal amine group of a protein or peptide, so that a homogeneous polyethylene glycol-protein or -peptide conjugate can be obtained in high yield. Unlike a prior art conjugate, the conjugate obtained according to the invention allows the decrease in the activity of the protein to be minimized without chemically modifying the protein, and thus the conjugate has an excellent pharmacological effect. Also, because the conjugate is homogeneous, the process for preparing the conjugate can be simplified. Moreover, the conjugate has uniform biological efficacy in vivo and shows strong resistance to hydrolysis and thus a long in vivo duration time.
