This is a general equation for the addition polymerisationof ANY alkene. The 'starter' molecule is called the monomer. WebFor the chemical industry, the most important alkenes are ethene, propene, and 1,3-butadiene. Where is alkene found? Alkenes are the raw materials for plastics such as polyethene, PVC, polypropylene, and polystyrene, among others. The chemistry of alkenes is present in unsaturated fats, beta-carotene, and light through vision
WebDuring the polymeriation of ethene, thousands of ethene molecules join together to make poly (ethene) – commonly called polythene. The reaction is done at high pressures in the presence of a trace of oxygen as an initiator. Some common addition polymers are listed in the Table below . Note that all the monomers have carbon-to-carbon double bonds.
