ADDITION POLYMERS

ADDITION POLYMERS Many reactions of organic compounds fall into four classes Substitution: an atom or group of atoms replaces another e g CH4 + Cl2 ⇒ CH3Cl + HCl Addition: two molecules react to form one e g C2H4 + Br2 ⇒ C2H4Br2 Elimination: one molecule reacts to form more than one e g C2H5OH ⇒ C2H4 + H2O

Addition Polymers

monomers to form a polymer is called polymerization Most polymerization reactions require a catalyst An addition polymer forms when unsaturated monomers react to form a polymer Ethene undergoes addition polymerization The ethene mol-ecules bond to one another to form the long-chain polymer polyethylene as described in the equation below

What are the uses and applications of Common polymers?
Know the uses/applications of common polymers. Addition polymerization and condensation polymerization are two modes of polymerization reactions in the formation of polymers. In addition polymerization, the monomer molecules bond to each other without the loss of any other atoms.
