Polymers from
Petrochemicals/Biomass
- Ethene
- Physical Properties= low mp/bp,
insoluble in water, non-conductor
- Double C=C bond-- very reactive
- Allows many addition reactions
- Allows many addition reactions
- From fractional distillation of Crude Oil
then 'Thermal or Zeolite cracking of
longer chains
