Structure of Polypropylene
Polypropylene is a thermoplastic made from propene or propylene monomer that is durable, rigid, and crystalline. It's a hydrocarbon resin with a linear structure. Polypropylene's chemical formula is (C3H6)n. Polypropylene plastic is one of the most affordable plastics on the market today.
Physical Properties of Polypropylene
The molecular weight and molecular weight distribution, crystallinity, form and proportion of comonomer (if used), and isotacticity all influence the properties of polypropylene. The methyl groups in isotactic polypropylene, for example, are oriented on one side of the carbon backbone.
Chemical Properties of Polypropylene
Apart from heavy oxidants, polypropylene is resistant to fats and almost all organic solvents at room temperature. PP containers may be used to store non-oxidizing acids and bases. PP can be dissolved in nonpolar solvents including xylene, tetralin, and decalin at high temperatures.

Effect of UV Exposure on Polypropylene Material
Polypropylene material when exposed to temperatures above 100 °C, its chain will degrade. Oxidation normally happens at the tertiary carbon centres, causing the chain to split due to an oxygen reaction. Cracks and crazing are signs of deterioration in external applications.
Effect of Microbes
Polypropylene degradation has been demonstrated by microbial communities isolated from soil samples mixed with starch. As implantable mesh products, polypropylene has been known to degrade in the human body. At the surface of mesh fibres, the damaged material forms a tree bark-like coating.
Synthesis of Polypropylene
The polymer is built around heterogeneous catalyst particles in gas-phase and slurry reactors. Propene is passed over a bed containing the heterogeneous (solid) catalyst during the gas-phase polymerization, and the resulting polymer is separated as a fine powder and then converted into pellets.
History
The history of polypropylene began in 1954 when a German chemist named Karl Rehn and an Italian chemist named Giulio Natta first polymerized it. This led to a large commercial production of the product that began just three years later. Natta synthesized the first syndiotactic polypropylene.

It is flexible and tough, especially when it is copolymerized with ethylene. This copolymerization allows this plastic to be used as an engineering plastic that is in a number of different products and uses.
History of Polypropylene
German chemist, Karl Rehn, and Giulio Natta first polymerized propylene to a crystalline isotactic polymer in March 1954. This discovery soon led to the commercial production of polypropylene starting in 1957. Others claimed the discovery, as often occurs when a general body of knowledge is used, and this litigation was not resolved until 1989.
What Polypropylene is Used For
Polypropylene is used for a wide number of different products.
