What is the polymer of poly[phenylethene]?
Ar
-[CH-CH2]-n
What are the typical uses of poly[phenylethene]?
Packing materials
Electrical insulation
What do plasticisers do?
Small molecules that get between polymer chains, forcing them apart and making them more flexible
Are polyalkenes biodegradable?
No due to the longer alkane backbone
Outline mechanical recycling?
Separate different types of plastics, wash them then grind them into small pellets, melted and remoulded
Outline feedstock recycling
The plastics are heated to a temperature that will break the polymer bonds and produce monomers which then can be used to make new plastics
