  • Patent number: 5391465
    Abstract: A method is provided for using selected photoactive compounds in acid hardening photoresists to produce thermally stable, high resolution images with near ultraviolet exposing radiation. These photoactive compounds can be used as photosensitizers for halogen-containing photoacid generators which by themselves do not otherwise generate sufficient acid upon exposure to near ultraviolet radiation to catalyze the crosslinking of acid hardening resins. The photoactive compounds are selected from the group consisting of phenothiazine, derivatives of phenothiazine, and phenoxazine.

  • Patent number: 5303029
    Abstract: A tubular test chamber of square cross-section minimizes reflection of stray light from the interior surface of the test chamber onto the detector during measurement by an optical system which is based upon right angle light scattering by the dust particles of a test sample. A rotary solenoid is utilized to open a trap door through which a sample is dropped into the test chamber during energization so that the internal spring of the solenoid can be used to bias the door closed upon deenergization thereof. The electronic circuitry which supports the measurement process provides an output in the form of a single "characteristic number" for each sample measured and has a novel feedback circuit used in auto-zeroing of the device.

  • Patent number: 5229456
    Abstract: A novel graft copolymer capable of imparting to a polyolefin when blended therewith high tensile modulus and high sag resistance without increasing melt viscosity, and a method of making the same. The graft copolymer is a polyolefin having a relatively high weight-average molecular weight methacrylate polymer grafted thereto. The graft copolymer is formed by dissolving or swelling a non-polar polyolefin in an inert hydrocarbon solvent, heating to dissolve the polyolefin, and while stirring the mixture, adding a methacrylate monomer, together with an initiator to produce a constant, low concentration of radicals, to form a graft copolymer with a high molecular weight polymer chain covalently bonded or grafted to the polyolefin backbone. The graft copolymer can be separated from the solvent, isolated by volatilizing the solvent, for example in a devolatilizing extruder, and extruded into a desired shape such as a sheet, tube or the like. This graft copolymer can be blended with a poolyolefin matrix.
