Its manufacture employs the same method today.

4 LDPE - Low-density polyethylene Low-density polyethylene (LDPE) is a thermoplastic made from petroleum. It was the first grade of polyethylene, produced in 1933 by Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization. Its manufacture employs the same method today. LLDPE - Linear low density polyethylene LLDPE is a substantially linear polymer with significant numbers of short branches, commonly made by copolymerization of ethylene with short-chain alpha-olefins (for example, 1-butene, 1-hexene and 1-octene). LLDPE has higher tensile strength than LDPE, it exhibits higher impact and puncture resistance than LDPE.

HDPE High Density Polyethylene In 1953, Karl Ziegler of the Kaiser Wilhelm Institute (renamed the ax Planck Institute) and Erhard Holzkamp invented high-density polyethylene (HDPE).

5 HDPE High Density Polyethylene In 1953, Karl Ziegler of the Kaiser Wilhelm Institute (renamed the ax Planck Institute) and Erhard Holzkamp invented high-density polyethylene (HDPE). The process included the use of catalysts and low pressure, which is the basis for the formulation of many varieties of polyethylene compounds. Two years later, in 1955, HDPE was produced as pipe. For his successful invention of HDPE, Ziegler was awarded the 1963 Nobel Prize for Chemistry. HDPE has little branching, giving it stronger intermolecular forces and tensile strength than LDPE

6 Production Process of LDPE (High Pressure Process) LyondellBasell (Lupotech) technology is the most used technology by LDPE plantsglobally. A close second is the Univation (Unipol) technology which is also used a lot for the production of LDPE worldwide.

13 PS Polystyrene Polystyrene was discovered in 1839 by Eduard Simon, an apothecary in Berlin. From storax, the resin of the Turkish sweetgum tree Liquidambar orientalis, he distilled an oily substance, a monomer that he named styrol. Several days later, Simon found that the styrol had thickened, presumably from oxidation; into a jelly he dubbed styrol oxide ("Styroloxyd").

14 Production Process of Polystyrene Solution (bulk) polymerization is commonly referred to as mass polymerization in the industry. The vast majority of all polystyrene produced today is produced via this technology. The common solvents used in this process are the styrene monomer itself and ethyl benzene. The two types of mass polymerization are batch and continuous, of which continuous mass is by far the most popular.

16 PP Polypropylene Polypropylene (PP) is one of the numerous derivatives of propylene CH3-CH=CH2. Depending on the type of polymerization and catalyst used, the polymers may present an orderly and disorderly configuration. Propylene was first polymerized to a crystalline isotactic polymer by Giulio Natta as well as by the German chemist Karl Rehn in arch 1954

17 Production Process of Propylene The two technologies primarily used to produce polypropylene are vapor- or gas- phase process and a slurry process that uses bulk slurry in liquid propylene as reaction medium. UNIPOL polypropylene process technology is a gas-phase technology that is occurred in a fluidized bed reactor system. The process is stable and predictable.

18 The Basell Spheripol process combines the bulk slurry reactor for producing homopolymers with the fluidized bed gas-phase reactor for heterophasic copolymers. In the process, a catalyst and cocatalysts are injected into pre-polymerization loop to initiate the polymerization.
