level questions: Addition Polymerisation

QuestionAnswer
How are Polymers made? What ever are they?-This is simply a very long Chain of Repeating Molecules, called Monomers -They simply Link Up, that's it
In Addition Polymerisation, what are the Type of Monomers used?-It is Molecules that have at least a Double Covalent Bond [Alkenes] between the Carbon Atoms [Unsaturated]
Explain how Ethene becomes Polyethene- What Conditions are needed?-The Double Covalent Bond in the Carbons breaks Up and becomes a Single bond which means it can connect with other Carbon Atoms, making a Repeat -a Pressure and a Catalyst needs to be Present for this to happen
In the Drawings of a Polymer, how can you make it Shorter?-Simply have the Monomer, and put Brackets around it, with an N on the Outside -This is simply a Term, so if it had 50 Monomers, you just Substitute it for N, and it will say 50 Lots for x -[C₃H₆]-n [Has to be drawn as a Displayed Formula]
Why is an Initiator and Heat needed for making Additional Polymers in a Labatory?-Since Alkenes don't really just Polymerise alone, it needs a Chemical to kick it off - this is the Imitator You might also need to Heat the Reaction Mixture with a Water Bath due to Additional Polymerisation involving Flammable Chemicals
How can you make Polystyrene? [Plastic found in Packaging]-Simply heat up Phenylethane [The Monomers] via a Water Bath with also a Chemical called Di-Dodecanoyl [The Initiator]
