C11 Flashcards
Polymers are
Long chains formed when lots of small molecules called monomers join together. This reaction is called POLYMERISATION (needs high pressure and a catalyst)
Condensation polymerisation involves
Monomers which contain different functional groups. The monomers react together and bonds form between them, polymer chains. For each new bond that forms, a small molecule is lost: this is why it’s called condensation polymerisation.
The simplest type of condensation polymers contain two different types of monomer, each with two
If the same functional groups
Addition polymerisation (number of types of monomers)
Only one monomer type containing ( C=C) bond.
Addition polymerisation (num of products)
Only one product formee
Addition polymerisation (functional groups involved in polymerisation)
Carbon-carbin double bond in monomer
Condensation polymerisation (num of tyoes of monomers)
- two monomer types each containing two of the same functional group
- one monomer type with two different functional groups
Condensation polymerisation (num of products)
Two types of products (the polymer and a small molecule)
Condensation polymerisation (functional groups involved in polymerisation)
Two reactive groups on each monomer
An amino acid contains
Two different functionak groups- a basic amino group (NH2) and an acidic carboxyl group (COOH)
Amino acids can form polymers
Known as polypeptides via condensation polymerisation
The amino group of an amino acid can react with
The acud group of another, and so on, to form a polymer chain. Every new bond that is formed a molecule of water is lost.
