Meeting Log 5

All present
Outside LT22, 2.30pm – 3.30pm, 22 March 2017
Agenda:

  1. Draft script 
  2. Video schedule

Script for first video (1.5mins):
Focus more on chemical concepts, brief introduction only.
Different polymerization
Different types of plastics, hard and soft, types of structures, properties

Script for 2nd Video (3mins):
Uses of Plastics: Packaging & Construction
Implications on SG: Land-fill Accumulation
Food Imitation
Monetary Costs (Transport of waste + landfills)
Pollution (Disposal)

SCRIPT FOR FIRST VIDEO:

Polymers are macromolecules that are composed of basic building blocks called monomers that are covalently bonded together. Polymers exist in our everyday lives and we use them daily without even knowing what they actually are. They range from Nylons in textiles and fabrics, to polyvinyl chloride (PVC) in pipes, just to name few of the many uses of polymers in our lives. The bottles of mineral water we purchase from supermarkets are also made of polymers.

(draw example of monomer and plastic objects – plastic bottle, PVC pipes, nylon rope, shirt)

The two main ways of forming polymers are addition and condensation. The addition process is a catalytic reaction between two unsaturated hydrocarbon monomers and no byproducts are formed. (draw addition reaction) Whereas condensation involves a removal of a water molecule for each amide and ester linkage. (draw out both amide and ester linkages as examples)

There are many different types of polymers!!!!!!!!!!!!!! And they can have very different properties?! For example, Polyvinyl chloride a.k.a PVC  which we are all familiar with, are strong and durable. (draw monomer) Hence, they are manufactured to make pipes. On the other hand, (draws hand) Polyethylene, a soft plastic, is commonly used in plastic bags (draw monomer and use real plastic bag). However, the only difference is that PVC has a additional chlorine atom in its monomer! As we can see, different types of polymers have different properties depending on their chemical configurations and the atoms present. (draw linear, branched and cross-linked)

To Do:
Research for the 2nd Video
Film the 1st video
Add media for blog

Next meeting:  29 March, 1.15pm at WKW.
