Polymers

3. the type of force between different polymers (which is what will be overcome during melting/boiling)
4. a natural polymer containing ester linkages
5. a substance containing a large number of atoms joined together by covalent bonds
8. a long-chain molecule that is formed by linking together many small repeating units known as monomers
12. the addition polymer used in plastic bottles, plastic bags, and clingfilm
14. polymerisation the process by which unsaturated monomers join together without the loss of any molecules or atoms to form a polymer
15. the process of joining together many small units (monomers) to form a large macromolecule (polymer)

1. cannot be broken down by bacteria and other decomposers; used to describe plastics
2. a natural polymer containing amide linkages
6. the process of burning hydrocarbons to form carbon dioxide and water
7. the type of bond between atoms of polymers
9. a synthetic plastic that contains a large number of amide linkages; used in clothings, parachutes, fishing lines, and rain coats
10. the process by which condensation polymers are broken down to form back monomers using dilute acid/alkali and high temperature
11. polymerisation the process by which molecules combine to form a polymer, with the loss of small molecules such as water or hydrogen halide
13. a synthetic plastic that contains a large number of ester linkages; used in clothings, curtains, and sleeping bags
