- 1What are the products of unsaturated alkenes when they undergo addition polymerisation?Long saturated chains with no double bonds
- 2Use of polymers (3)i. Combustion for energy production
ii. Use as organic feedstock for production of plastics
iii. Removal of HCl formed during disposal by
combustion of halogenated plastics - 3Benefits of biodegradable polymersBroken down by MO into water,co2, and bio compounds
- 4Benefits of bioplasticsAlternative to oil-based products
Renewable energy e.g. plant starch - 5Photodegradable polymersContain bonds weakened by absorbing light to start degradation
