  • Patent number: 5502089
    Abstract: A crosslinkable polymeric emulsion has a pH from about 1.5 to about 8.5 and includes a carboxyl-substituted latex polymer dispersed in an aqueous medium, an Iron (III) compound and an amount of a stabilizer, selected from the group consisting of nonionic surfactants and protective colloids, effective to sterically stabilize the emulsion. A method for making a crosslinked polymer film includes forming a layer of the crosslinkable polymer emulsion and drying the layer to form the crosslinked polymer film wherein the film is ionically crosslinked between carboxyl substituent groups of the polymer by Iron (III) cations. A crosslinking agent for carboxyl-substituted polymers includes particles of a water-insoluble Iron (III) compound having an average maximum characteristic linear dimension of less than or equal to about 5 microns.

  • Patent number: 5419088
    Abstract: The invention describes plastic automobile windows that are safe during side impact collisions, including a method for installing the windows into the motor vehicle. The mounting system and window material will contain an occupant in a vehicle at low to moderate head impact velocities. The occupant is not subjected to head injuries. The occupant is not subject to lacerations.The window design uses a high modulus transparent thermoplastic, having an abrasion resistant coating. The window is attached to the window opening in a motor vehicle by using one of several mounting techniques as described herein. For fixed windows, the mounting systems will bond the window to the vehicle under normal operating conditions and provide a weather seal. For a movable window, the window frame will be equipped with a sliding track and provide a weather seal. A groove or notch in the window material inward from the edge in combination with the mounting systems enhance a safe release of the plastic window.
