Macromolecules

• Polymers are made by addition and condensation of monomers.
• Condensation reactions involve the loss of water molecules during polymerization.
• Addition polymerization is the process of joining monomers together to form a long chain of polymer molecules.
• Addition polymerization involves the breaking of c=c double bonds.
• Poly(ethene) makes plastic bags and clingfilm.
• Polyamide: a synthetic polymer of a type made by the linkage of an amino group of one molecule and a carboxylic acid group of another, including many synthetic fibres such as nylon.
• Polyester: A polymer made from esters of dicarboxylic acids and alcohols makes terylene a synthetic fibre.
• Nylon and Terylene can be used to make sleeping bags , curtains ,clothing, fishing lines and parachutes.
• Monomer - small molecule that joins with other similar molecules to form polymers
