Which statement describes condensation polymerisation?
Monomers with a C=C\mathrm{C{=}C}C=C bond join together and no other product is made at each link.
Monomers with two functional groups join and a small molecule, such as water, is lost at each link.
Monomers with one functional group join together and water is added at each link.
Monomers join when their C=C\mathrm{C{=}C}C=C bonds break and hydrogen is lost at each link.
