Polymerisation
What feature of alkene molecules allows them to act as monomers?
The presence of carbon atoms
The C=C bond
The presence of hydrogen atoms
Functional Groups at either end of molecule
Define polymer
circular molecule made with many repeating units
short molecule made of a few repeating units
long, chain-like molecule made of repeating units
chain-like molecule that contains hydrogen and oxygen
What happens in a Condensation Polymerisation reaction?
All atoms used up when monomers join together
A small molecule is added
Two different functional groups bond together and expel a small molecule (often water)
The C=C bond is broken to form a long chain of repeating units
Type of polymerization reaction which breaks the double covalent bond of monomers
addition polymerization
condensation polymerization
