    Abstract: Improved polymer-immobilized photosensitizer are disclosed as well as methods of preparing and using them. The polymer-immobilized photosensitizers comprise a cross-linked polymer backbone, a plurality of cationic ammonium or phosphonium groups covalently bound to the polymer backbone and an immobilized photosensitizer. The average total number of carbon atoms in the ammonium or phosphonium group is at least four and preferably at least 12. The photosensitizer can be either covalently or ionically bound to the polymer. Polymer-supported photosensitizers of the invention are unexpectedly superior in catalyzing the photosensitized oxidation of compounds containing carbon-carbon double bonds.

    Abstract: A modified ethylene−vinyl alcohol copolymer (C) having an ethylene content of 5 to 55 mol %, which contains a specific structural unit (I) in an amount of 0.3 to 40 mol % and may be obtained by reacting an ethylene−vinyl alcohol copolymer (A) with a monovalent epoxy compound (B) having a molecular weight of 500 or less; and a method for producing the modified ethylene−vinyl alcohol copolymer (C) which comprises melting and kneading an ethylene−vinyl alcohol copolymer (A) with a monovalent epoxy compound (B) in an extruder. The modified ethylene−vinyl alcohol copolymer (C) is superior to a non−modified ethylene−vinyl alcohol copolymer (A) in transparency, stretchability, softness and flexing resistance due to the specific structural unit (I) incorporated therein, and thus, can be used as a barrier material in various applications requiring the above performance capabilities.

    Abstract: A novel fluorinated aromatic acetal polymer comprises at least one unit of A and at least one unit of B or C, or at least one unit of each of A, B and C and optionally further comprises at least one unit of either D or E or at least one unit of each of D and E, wherein the units A and B and/or C, and optionally D and/or E are linked together by single covalent C-C bonds and have the formulae (A), (B), (C), (D) and (E), wherein R A is H or C 1 -C 11 alkyl, or an aryl group that does not contain fluorine, and R B and R C are an aryl groups that contains fluorine. The polymer is prepared by reacting a hydrolyzed polyvinyl acetate polymer or copolymer with at least one non-fluorinated aldehyde component, and at least one fluorinated aromatic component. The polymer is useful is preparing a photosensitive composition which comprises at least one diazo resin and at least one such fluorinated aromatic acetal polymer. Such a photosensitive composition may be applied to a support to form an imageable member which may be imaged to form a lithographic printing plates.
