Polypropylene: A Summary And Analysis
Polypropylene consist of propylene as the monomer which has three carbons and one double bond between two of those carbon atoms. Polypropylene is manufactured from propylene gas in the presence of a catalyst. They are widely used for pipes, containers and packaging. Nonetheless, Polyethylene is a polymer made of ethylene. Ethylene has two carbon atoms bonded to each other with a double bond. Polyethylene is the basic component in making bottles, bags and fibres. Both polypropylene and polyethylene are thermoplastics polymers. They are linear polymers at which the chains aligned properly giving a range of molecular weights and arrangement of molecules pack together in variety of configurations. (Michael & David, 2013)
