    Abstract: The invention is a photoswitchable benzocyclobutene-based polymer that while remaining aqueous developable, avoids the problem of significant moisture uptake. The oligomer or polymer comprises a polymeric backbone, benzocyclobutene reactive groups, and photoswitchable pendant groups. The pendant groups are bonded to the polymeric backbone and are characterized by the presence of a moiety that converts to carboxylic acid upon exposure to activating wavelengths of radiation a carboxylic acid. When the oligomer or polymer is subsequently heated to cause cure of the oligomer or polymer, carbon dioxide is emitted and the group forms a substantially non-polar moiety. The invention is also a method of making such a polymer and a method of forming a patterned film using such a polymer.

    Abstract: A method for modifying the properties of a nylon block copolymer comprising: supplying a nylon block copolymer wherein the nylon block copolymer has a flexural modulus, a tensile modulus, and an unnotched Izod impact strength. Incorporated into the nylon block copolymer is a nanoclay filler wherein the nanoclay filler is present at a level of between about 1.0-20.0 wt. %. The addition of the nanoclay filler serves to increase the values of the nylon block copolymer's flexural modulus, tensile modulus, while substantially maintaining the value of the unnotched Izod impact strength and/or increasing the value of said unnotched Izod impact strength, upon addition of the nanoclay filler.

  • Publication number: 20020045716
    Abstract: Copolymers of polycarbonates or polyarylates with polyether polymers such as polyethersulfones, polyetherketones, and polyetherimides are prepared by reaction of the polyether polymer-forming reagents, e.g., bisphenol A disodium salt and bis(4-chlorophenyl) sulfone, in the presence of the polycarbonate or polyarylate. The reaction may take place in a dipolar aprotic solvent, or in a water-immiscible aromatic solvent in the presence of a phase transfer catalyst, preferably a hexaalkylguanidinium halide. Hydroxy-terminated polyether oligomers may be produced from the copolymers by saponification of carbonate or ester groups.
