Green polymer chemistry
WebIn the polymer industry, the production of off-spec material is not unusual. The viscous nature of high molecular weight polymers and the typically exothermic nature of the reaction make the polymerization process prone to temperature excursions. These excursions can affect the polymer molecular weight and lead to WebOct 20, 2013 · Our studies on green polymer chemistry have been performed mostly on polymer synthesis using enzymes as catalyst (''enzymatic polymerization'') and …

WebThis book reviews the latest research, development, and future potential of polyimides and green polymer chemistry. It combines the major interdisciplinary research in this area. Polymers with imidic structure, known as polyimides, are widely investigated owing to their practical implications in numerous industrial sectors. WebOct 3, 2005 · A group at the University of Nottingham, in England, led by chemistry professor Steven M. Howdle, combines two green approaches to polymer synthesis. "We use a clean solvent-supercritical carbon dioxide-and a natural catalyst, that is, an enzyme, to make unusual block copolymers," Howdle explained.
WebOct 10, 2024 · Another way to demonstrate solvent welding of polymers with strandlike macroscopic structures is the use of polylactic acid (PLA). This polymer, like cellulose and starch, can be sourced from plants and is considered to be a green polymer. PLA is often used in 3-D printing.
