Abstract: Fibrous dressings employed as wound contacting materials, may be rendered hypoadherent by coating the body contacting surface with a polymeric coating of a material such as a siloxane block copolymer or a blend thereof with an amine extended polyurethane.
Abstract: A method is provided for reducing the force required to move a pipe through a J-tube attached to an offshore platform by coating the pipe with hydrophilic polymer and then moving the pipe through the J-tube, or by introducing a solution of hydrophilic polymer and water into the J-tube and then moving the pipe through the J-tube.
Abstract: Disclosed are a coating composition (A) for preventing adhesion of organisms which comprises as its vehicle component a homopolymer or a copolymer, the homopolymer being one prepared by homopolymerizing a phenol-modified unsaturated monomer obtained by reacting (a) an unsaturated monomer containing epoxy group and/or hydroxyl group with (b) an addition reaction product of a phenolic compound with a compound having one carboxylic anhydride group per molecule, and the copolymer being one prepared by copolymerizing said phenol-modified unsaturated monomer and a radically polymerizable unsaturated monomer, and also a coating composition (B) for preventing adhesion of organisms which comprises as its vehicle component a phenol-modified resin prepared by reacting (c) a resin containing epoxy group and/or hydroxyl group with (b) and addition reaction product of a phenolic compound with a compound having one carboxylic anhyhdride group per molecule.

Abstract: The invention provides a blend of metal oxide, such as silicon oxide, with etheric phosphazene. The invention optionally contains salt for antistatic coatings. The composition of the invention is formed by preparing solutions of etheric phosphazene and alkoxysilane, such as tetraethoxysilane. The solutions are then coated onto suitable substrates, or cast films and cured at room temperature or with moderate heating. The coatings and films produced are transparent, tough, hard, and flexible. They are multicomponent blends of the silicon oxide and phosphazene. It is also within the invention to form the blends with other metal oxides, rather than silicon, such as titanium, aluminum, or zirconium. The composite may be doped with low lattice energy salts to form antistatic composites.

Abstract: Molding compositions, easily shaped into useful articles having improved mechanical properties that are less anisotropic, contain (a) a thermotropic polymer, and (b) an inorganic filler material, such inorganic filler (b) being a crystalline inorganic filler of platelet shape having a mean diameter ranging from 0.5 to 400 .mu.m and a shape factor represented by the ratio: ##EQU1## which ranges from 10 to 90, and such inorganic filler (b) being present in an amount, expressed in % by weight of filler in the combined polymer+filler, ranging from 20% to to 60%, with the proviso that such amount ranges from above 50% to 60% when the mean particle diameter of the filler material is less than 20 .mu.m.
Abstract: A thermosensitive image transfer recording medium is disclosed, which comprises (i) a heat-resistant support and (ii) a thermofusible ink layer formed on the support, comprising as the main components (a) a binder agent comprising as the main component a low-molecular-weight mixed polyamide having an ether linkage therein, having the formulas,CO--X--COHN--Y--NH (A),CO--X--COHN--Y'--NH (B), andCO--X--CO--Y" (C)wherein S, Y, Y' and Y" are defined in the specification, and (b) a coloring agent.
Abstract: A process is disclosed for producing a semicrystalline polymer composite form which exhibits high strength and low electrical resistivity. Polyether-etherketone PEEK) powder and 4 to 10 volume percent a hard metal powder are blended and then compacted at room temperature to a relative green density greater than 60%. The resulting preform has an electrically conductive segregated network of metal particles throughout a PEEK matrix.
