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
- From fractional distillation of Crude Oil then 'Thermal or Zeolite cracking of longer chains
- Ethene+ Ethene= Polyethylene
- LD polyethene= high pressure/temp, "Initiator chemica"= cling wrap
- HD Polyethene= low pressure/temp, catalyst=toys
- Chloroethene=polyvinylchloride/PVC
- ethenylbenzene=polystyrene
Biopolymers
- Cellulose+glucose+ethanol=Ethene
- Polyhydroxybutyrate (PHB)
- B. Magaterium
