  • Patent number: 9151408
    Abstract: The method of preserving the anodized finish of a barrier door of a process module includes bonding a seal to a metal surface, anodizing the metal surface, and then using a CNC machine to polish the metal surface without damaging the seal. The metal surface is polished by traversing a polishing path along the metal surface with a polishing head maintaining frictional contact with the metal surface. The integrity of the seal is preserved by bounding the polishing head to skirt the edge of the seal by following the polishing path.

    Abstract: Brominated styrene-butadiene copolymers are recovered from solutions in a halogenated solvent by an anti-solvent precipitation process. The precipitation process is performed by adding the anti-solvent to the brominated styrene-butadiene copolymer solution. By performing the precipitation using this specific order of addition, a denser product is obtained that is easier to dry. The recovered product shows a reduced tendency to act as a nucleating agent when it is used as a flame retardant additive in an extrusion foaming process.

  • Patent number: 6838530
    Abstract: The invention provides a method of making a number of different multifunctional acrylic materials from a limited number of starting materials. The method of the invention requires the product of a masterbatch of an acrylic oligomer or polymer having two or more cyclic carbonate functional groups. A first portion of the masterbatch is then reacted with ammonia and a grafting material (c) in either successive or simultaneous reactions to provide a first multifunctional acrylic oligomer or polymer. Additional portions of the masterbatch may be reacted with ammonia and other grafting materials (c), different from the first grafting material (c), in either successive or simultaneous reactions to provide different multifunctional acrylic oligomers or polymers.

  • Patent number: 6835782
    Abstract: A polymer having a structure of the formula: in which X, Y and Z represent independently each other H, F, Cl, Br or I, provided that at least one of X, Y and Z is F; R represents a straight or branched fluorinated alkylene group which may contain an oxygen atom; x and y represent mole percentages and x is from 1 to 100% by mole; A is —CN, —NCO, —COOR′ in which R′ is H or an alkyl group having 1 to 10 carbon atoms, an acid anhydride group or an unsaturated hydrocarbon group; and M is a repeating unit derived from a copolymerizable monomer is treated with a crosslinking agent selected from ammonia, diamines and polyol compounds and crosslinked through the side functional groups of the polymer. This crosslinking method can be carried out at room temperature and provides a transparent fluoropolymer having better heat resistance than conventional transparent thermoplastic resins.
