    Phillips Petroleum chemists J. Paul Hogan and Robert Banks first demonstrated the polymerization of propylene in 1951. The stereoselective polymerization to the isotactic was discovered by Giulio Natta and Karl Rehn in March 1954. This pioneering discovery led to large-scale commercial production of isotactic polypropylene by the Italian firm Monte...

    Polypropylene is in many aspects similar to polyethylene, especially in solution behavior and electrical properties. The methyl group improves mechanical properties and thermal resistance, although the chemical resistance decreases.: 19 The properties of polypropylene depend on the molecular weight and molecular weight distribution, crystallinity, ...

    Polypropylene is produced by the chain-growth polymerization of propene: The industrial production processes can be grouped into gas phase polymerization, bulk polymerization and slurrypolymerization. All state-of-the-art processes use either gas-phase or bulk reactor systems. 1. In gas-phase and slurry-reactors, the polymer is formed around hetero...

    Melting process of polypropylene can be achieved via extrusion and molding. Common extrusion methods include production of melt-blown and spun-bond fibers to form long rolls for future conversion into a wide range of useful products, such as face masks, filters, diapers and wipes. The most common shaping technique is injection molding, which is use...

    As polypropylene is resistant to fatigue, most plastic living hinges, such as those on flip-top bottles, are made from this material. However, it is important to ensure that chain molecules are oriented across the hinge to maximise strength. Polypropylene is used in the manufacturing of piping systems, both ones concerned with high purity and ones ...

    PP objects can be joined with a two-part epoxyglue or using hot-glue guns. PP can be melted using a speed tip weldingtechnique. With speed welding, the plastic welder, similar to a soldering iron in appearance and wattage, is fitted with a feed tube for the plastic weld rod. The speed tip heats the rod and the substrate, while at the same time it p...

    The advocacy organization Environmental Working Group classifies PP as of low to moderate hazard.[why?]PP is dope-dyed; no water is used in its dyeing, in contrast with cotton.

    Like all organic compounds, polypropylene is combustible. The flash point of a typical composition is 260 °C; autoignition temperatureis 388 °C.

    In mammals and other animals, the vagina ( pl.: vaginas or vaginae) [1] is the elastic, muscular reproductive organ of the female genital tract. In humans, it extends from the vestibule to the cervix. The outer vaginal opening is normally partly covered by a thin layer of mucosal tissue called the hymen. At the deep end, the cervix (neck of the ...
