Can ethene produce a polymer
WebTHE POLYMERISATION OF ALKENES. This page looks at the polymerisation of alkenes to produce polymers like poly (ethene) (usually known as polythene, and sometimes as polyethylene), poly (propene) (old name: polypropylene), PVC and PTFE. It also looks briefly at how the structure of the polymers affects their properties and uses. WebApr 14, 2024 · According to an industry source, bio-based plastic production in 2024 marked 4.5 million tons, with an expected compound annual growth rate of 14% up until 2027. Bio-propylene can be used as an eco-friendly raw material for various plastic products and is expected to play a pivotal role in the rapid growth of the bioplastic market.
