Using Alkenes To Make Polymers Flashcards
What is the most useful thing you can do with alkenes?
Polymerisation
What is polymerisation?
The joining together of lots of small alkene molecules to form very large molecules known as polymers
What can ethene molecules be joined up to make?
Polyethene
What does a polymers physical properties depend on?
What it’s made from
The temperature and pressure of its polymerisation
What is the difference between polyethene made at high temperature and pressure to polyethene made at low temperature and pressure
The high one is flexible with a low density
The Low one is rigid and dense
What are some uses of polymers?
Plastic bags
Dental polymers
New biodegradable packaging
Memory foam
Why do most polymers not rot?
They’re non biodegradable making it difficult to get rid of them which is why we recycle them
Why will crude oil products like polymers get more expensive?
They’re cheap at the minute but as crude oil begins to run our prices will rise
What is an example of a smart polymer?
Memory foam as it can retain its shape
