polymerization in living and non-living systems STS: 2) Illustrate how science and technology are developed to meet societal needs and expand human capabilities STS: 3) Illustrate how science and technology have both intended and unintended consequencesPolymerization
...Polymers are large molecules made of chains of monomers, small molecules that link together.Polymerization is the formation of
polymers from these small unitsPolymers can occur naturally (proteins,
carbohydrates) and can be synthesized (nylon, Teflon, polyethylene)They play an integral part in the
function of life systems and have revolutionized the way society functionsAddition Polymerization
...Many plastics (synthetic polymers) are made by this process ...The polymerization process is initiated with a free radical (a species with an unpaired electron). The free radical attacks and breaks the double bond forming a new free radical that attacks another monomer ...Addition Polymerization always results in one product, the polymer ...Requires unsaturated hydrocarbon monomers and bond saturation occurs when the polymer is made ...Common polymers produced by addition polymerization: ...The polymer names end in ²ene (i.e. polystyrene, polypropene). Does this mean they have double bonds? No, the double bonds are saturated by adjacent monomers, as the polymer is made. The name refers to the starting monomer (i.e. polyethene is started by the monomer ethene) ...What properties make Teflon a good product for non-stick materials? Teflon is made up of C-F bonds which are very strong (not C-H bonds). These very strong bonds make the Teflon highly unreactive (non-sticking), it has a high melting point and it has a slippery surfaceCondensation Polymerization
...Monomers combine to form a polymer and a bi-product. Each time a bond forms between monomers, small molecules, such as water, ammonia, or HCl MUH ´ŃRQGHQVHGµ RXPB ...The polymerization of nylon:For condensation polymerization
to occur, monomers must be bifunctional, meaning they have at least two functional groups.If they only had one functional
group, then only one bond would form.Condensation Polymerization
...Condensation polymerization also produces natural polymers, called proteins. ...Amino acids (monomers) polymerize to make peptides (short chains of amino acids) or proteins (long chains of amino acids)Comparison of Addition and
Condensation Polymerization
...Needs a double or triple bond in the monomer ...Produces only one product, the polymer ...Needs bifunctional monomers (have two functional groups) ...Produces two products: the polymer and the biproduct (water, ammonia or HCl)Addition Condensation
Polyester
...When a carboxylic acid reacts with an alcohol in an esterification reaction, a water molecule is eliminated and a single ester molecule is formed. ...This esterification reaction can be repeated so many esters areÓRLQHG LQ M ORQJ ŃOMLQ" M polyester
This is created using a dicarboxylic acid (an acid with a carboxyl group at each end) and a diol (an alcohol with a hydroxyl group at each end) The ester linkages are formed end to end between alternating acid and alcohol moleculesPolyester: Dacron
...Another example of a polyester: Note the two carboxyl groups in the dicarboxylic acid and the two hydroxyl groups in the polyalcohol that start the chain reactionNatural Polymer Examples
