Title: Controlling slip of polymer films
Inventor: WILEY RALPH MCCONNELL
IPC: C08J7/046
Filed: 1965-03-18
Abstract: In order to control the coefficient of slip of a synthetic organic polymer film, an aqueous emulsion or suspension containing particulate solid material is sprayed towards at least one surface of the film, water being evaporated from the emulsion or suspension during its travel towards the surface of the film to effect deposition on the film of spray-dried particulate solid material the particles of which have an average diameter of from 0.2 to 40 microns, preferably from 0.8 to 8 microns.  The film preferably is disposed in the horizontal plane, the surface thereof being sprayed from above.  In order to provide uniform deposition of the particulate material on the film, an electrostatically charged plate may be positioned below the film; alternatively, the film itself may be electrostatically charged by passing between a grounded idler roller and an array of corona needles and thereafter sprayed with particulate material carrying an opposite charge which has been obtained either by keeping the spray nozzle at a suitable potential or by generating a corona discharge between the spray nozzle and the film.  It is preferred for the spray to be given an electrostatic charge and to be attracted towards the surface of the film by an oppositely charged electrode.  The particulate solid material may be rice starch, a polymer of styrene, vinyl toluene, divinyl benzene, methylmethacrylate or mixtures thereof, for example a copolymer of styrene and divinyl benzene, or a copolymer of such monomers with other ethylenically unsaturated monomers, for example a copolymer of styrene and 1,3-butadiene containing less than 30 per cent by weight butadiene.  The emulsion or suspension, which may be obtained by seeded emulsion polymerization or by suspension polymerization, also may contain wetting agents, emulsifiers, antistatic agents, limited amounts of metal salts, catalyst and other residues from emulsion or suspension polymerization.  The particulate solid material may be deposited on both surfaces of the film, but preferably deposition is on one surface only, the other surface becoming coated by transfer on wind-up of the treated film.  The particulate solid material may be deposited on the surface of a thermoplastic polymer film, for example either on the surface (or surfaces) of a self-supporting film or on an external thermoplastic film layer of a laminate structure; the polymer from which the film is made may be polystyrene, polyethylene, polypropylene, polyethylene coated with polypropylene, polypropylene coated with polyethylene, polypropylene coated with a copolymer of vinyl chloride and vinylidene chloride, a copolymer of ethylene and propylene or of vinyl chloride and vinylidene chloride or of styrene and butadiene, or a terpolymer of ethylene, propylene and vinyl acetate or of ethylene, propylene and ethyl acrylate.
