    Poly(chloroethene) (Polyvinyl chloride)

    The catalyst generally used is a mixture of copper(ll) and potassium chlorides, deposited on alumina. As the reaction is highly exothermic, the reactor vessel is cooled to give the optimum reaction temperature and to reduce unwanted by-product formation of, for example, chloroethane and 1,1,1,2-tetrachloroethane. 95% conversion of ethene to 1,2-dichloroethane is obtained

    Polymerization is the process of combining many small molecules known as monomers into a covalently bonded chain or network. During the polymerization process, some chemical groups may be lost from each monomer. This happens in the polymerization of PET polyester.The monomers are terephthalic acid (HOOC—C 6 H 4 —COOH) and ethylene glycol (HO—CH 2

Potency determines how high the pressure must be for miasma production to work. 50-60 potency is needed in standard pressure. Yield determines the output rate of the miasma. Harvesting does not yield any fruits
