How Polymers are Made

WebIn the laboratory ethene is prepared by dehydration of ethanol. On heating ethyl alcohol with sulphuric acid at a temperature of 170 ° C temperature forms ethene. What is produced when ethene reacts with steam? The reaction of ethene with steam to form ethanol can be reversed. This allows ethanol to be converted into ethene. WebSynthetic Polymers These are man-made polymers. Plastic is the most common and widely used synthetic polymer. e., Nylons, Polythene, PVC, Synthetic rubbers, etc. ...
