OR, WHAT TO DO WITH THE ALKENESMADE IN CRACKING.POLYMERISATION INVOLVES TAKING A SINGLE ALKENE MOLECULE (WECALL THIS A MONOMER) AND STICKING IT TO OTHER IDENTICALMOLECULES (MONOMERS) TO MAKE A CHAIN. WE CALL THIS CHAIN APOLYMER!nHWHAT ELSE DO I NEED TO KNOW??Well, you need to know how to represent polymerisation in the form of a diagram (seebelow)HC C C CHHn H HThis is a monomer. Theletter n represents thenumber of monomerswhich will be joinedtogetherHHThis is a polymer. The letter n represents thenumber of monomers which have been joinedtogether. The brackets must be drawn. Also,notice how the double bond has disappeared.


I am confused. Why are there so many names for polymers and what do they mean?This is a common question. But also so easy to answer. The names of all Polymersbegin with the word poly. The ending of the name is simply the same as the alkenemonomer.Example: If we make a polymer out of the alkene propene, it’s name will bepolypropene.Can you write down the names of the polymers made from the following monomers?MonomerPolymerEtheneButeneHexeneThis is a simple process. High temperatures andof course a catalyst to speed up the reaction are allthat are needed.
