Polypropylene (PP) Production and Manufacturing Process

09/06/2010  The first commercial production of polypropylene was in the 1950s following the discovery of Ziegler-Natta catalysts. It was produced initially in a slurry process where propylene is reacted in the presence of a catalyst in solvent to produce a mixture of crystalline and amorphous polymer. The disadvantage of this route was that the catalyst had to be treated with alcohol to

Polypropylene - Wikipedia

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