Plastic and Chemistry?

How does Plastic relate to at least 3 topics in Chemistry in the listed below:

Structure & properties

Organic Chemistry

Energy Changes and Rates of Reaction

Chemical Systems and Equilibrium

Electrochemistry

An explanation would help too

Update:

How it relates to Processing of plastics, plastic itself, etc.

Also there are actually many types of Plastics, which type of plastic could explain more of these topics?

    Plastics relate to structure and properties of chemicals since they are macromolecules. They form very large scale molecules whose physical properties are defined by their chain length. These help define properties like their solidity and plasticity, ability to be shaped and moulded,

    They relate to organic chemistry due to a polymerisation reaction, forming from organic monomers that contain a "unsaturated" double bond.

    Energy changes and rates of reaction are involved since typically a polymerisation reaction will occur spontaneously forming the polymer. However, most polymerisation reactions are not favoured naturally but require the presence of a catalyst to favour the formation of the polymer. Once create most polymers are very stable. Rate of reaction is usually defined from the monomer concentration, temperature, but primarily on the presence of a catalyst.

    The processing of plastics will be determined by the structure and properties. Also the properties and chemistry of the plastic will determine whether the process leads to degradation of the plastic. Similarly the rate of reaction and type of formation of the plastic will effect the sorts of processing that can be applied.

    If you wanted to study a couple of plastics, I'd chose polyester (chain growth synthesis) and polyethylene (step growth synthesis).

    Hopefully this is enough to get you started.

    Enjoy :)
