addition polymers (synthetic polymers)
No description yet. This curated deck is ready for daily study.
Card preview (13)
what are polymers
large molecules of high relative mass
addition polymers are made by
linking large numbers of monomers
process of making polymers is called
polymerisation
each monomer is what and attached to adjacent units via?
a repeat unit covalent bonds
to make addition polymers, whats needed (2)
high pressures and a catalyst
what everyday materials are polymers
resin, polystyrene and plastics
what are synthetic polymers
polymers that are man-made (manufactured) by humans,
when drawing a polymer, make sure (2)
that the repeating units stick out of the brackets and that there’s an n at the bottom
how do you know in drawings when its a monomer or polymer
polymers have repeat units
what makes addition polymers unreactive and inert
the small molecules with strong bonds in them
do addition polymers biodegrade easily
no
landfills
waste polymers are disposed into landfill sites but as they decompose very slowly sites fill up quickly and valuable land is taken up
incineration (3)
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
