Polythene is a synthetic polymer made from the monomer ethylene. It is a thermoplastic, meaning that it can be melted and molded. Polyolefin is also a synthetic polymer, but it is made from a different monomer, usually propylene. It is also a thermoplastic. Both polythene and polyolefin are used in a variety of applications, including packaging, insulation, and construction materials. The main difference between the two polymers is their structure. Polythene has a linear structure, while polyolefin has a more branched structure. This gives polyolefin better strength and resistance to heat and chemicals than polythene. As a result, polyolefin is often used in applications where higher temperatures or harsher chemicals are present.
