Polymers

Question 1

What is addition polymerisation?

Answer 1

The formation of a very long molecular chain by repeated addition reactions of many unsaturated alkene molecules

Question 2

How do you draw the monomer?

Answer 2

With a double bond between carbons then the rest of the molecule with an ‘n’ on the middle left

Question 3

How do you draw the repeat unit?

Answer 3

With the C-C bond in the centre, the other bonds vertical and one bond from either side of the C crossing the outer square brackets. Also, a small ‘n’ on bottom right hand corner

Question 4

How do you show bonds between each monomer with skeletal formula?

Answer 4

With wiggly lines

Question 5

What are the 2 methods of polymer disposal?

Answer 5

Landfill and processing

Question 6

What are the two ways polymers are processed?

Answer 6

Used as organic feedstock for the production of plastics and other organic molecules or used as a fuel to produce energy

Question 7

What are the 3 types of novel polymers

Answer 7

Bio plastics, biodegradable polymers and photodegradable polymers
