WebHow are they made and the types of polymer reactions to do so. There are two main polymerization processes; 1. Addition/chain reaction. When multiple ethene molecules react with the presence of a catalyst (e.g. Platinum), polyethene is made by the breaking of the (pi) double bonds in which forms the monomers into a chain (Sharpe, 2015). WebEthene is the unsaturated monomer which, when joined to other ethene molecules through an addition reaction, forms the saturated polymer polyethene. Polyethene is the most common plastic with over 80 million metric tons produced each year. It is commonly known as polyethylene. It is cheap and is used to make squeeze bottles, plastic bags, films ...

If you add aqueous NaOH (instead of alcoholic) you will get substitution reaction - i.e Br will be replaced by OH - so be careful here! Hope it helps! PS -Aqueous means solvent for NaOH... WebEthene combines directly with the halogens, e.g., with chlorine to form 1,2-dichloroethane (commonly known as ethylene dichloride). With hydrogen it forms ethane . It is readily absorbed by sulfuric acid to give ethyl hydrogen sulfate; if the reaction is carried out under pressure, diethyl sulfate is largely formed. coach willingham coaching now
