Addition polymerisation

Question 1

what is the monomer of an addition polymer

Answer 1

alkene

Addition polymers are quite unreactive

Question 2

are poly alkene chains polar or non polar?

Answer 2

non polar

Question 3

what type of forces hold the addition polymer chains together

Answer 3

VDW

the longer the polymer chain the more vdw forces there are.

Question 4

when can a polymer be polar

Answer 4

when it contains Cl

these polymers will have a permanent dipole dipole force

Question 5

How do plasticisers affect polymers

Answer 5

They make the polymer more flexible
the plasticiser molecules get BETWEEN the polymer chains and push them apart
reducing the strength of the intermolecular forces between the chain.

Question 6

plasticised PVC vs Rigid PVC

Answer 6

plasticised pvc is much more flexible and is used to make electrical cable insulation, clothing, flooring tiles
Rigid PVC is used to make drainpipes and window frames
