addition polymers (synthetic polymers)

Question 1

what are polymers

Answer 1

large molecules of high relative mass

Question 2

addition polymers are made by

Answer 2

linking large numbers of monomers

Question 3

process of making polymers is called

Answer 3

polymerisation

Question 4

each monomer is what

and attached to adjacent units via?

Answer 4

a repeat unit

covalent bonds

Question 5

to make addition polymers, whats needed (2)

Answer 5

high pressures and a catalyst

Question 6

what everyday materials are polymers

Answer 6

resin, polystyrene and plastics

Question 7

what are synthetic polymers

Answer 7

polymers that are man-made (manufactured) by humans,

Question 8

when drawing a polymer, make sure (2)

Answer 8

that the repeating units stick out of the brackets and that there’s an n at the bottom

Question 9

how do you know in drawings when its a monomer or polymer

Answer 9

polymers have repeat units

Question 10

what makes addition polymers unreactive and inert

Answer 10

the small molecules with strong bonds in them

Question 11

do addition polymers biodegrade easily

Answer 11

no

Question 12

landfills

Answer 12

waste polymers are disposed into landfill sites but as they decompose very slowly sites fill up quickly and valuable land is taken up

Question 13

incineration (3)

Answer 13

polymers release a lot of heat when they burn and produce co2 which contributes to climate change

polymers which contain chlorine like PVC release toxic hydrogen chloride when burnt

if incinerated by complete combustion then carbon monoxide released
