WebSynthetic plastic is made by a reaction known as polymerisation, which can be performed in two different ways: Addition polymerisation : Synthesis includes adding together monomers in a long chain. One monomer connects to the next and so on, when a catalyst is introduced, in a process known as chain growth polymers, adding one monomer unit at a time. WebPolypropylene is a polymer whose monomer is propylene (an organic hydrocarbon with the chemical formula C 3 H 6 ). The chemical formula of polypropylene is (C 3 H 6) n. This polymer is also known as polypropene and is often denoted by the abbreviation ‘PP’. Generally, polypropylene is produced via a chain-growth polymerization reaction ...
