Condensation polymers

• What process forms polysaccharides?

  Condensation polymerisation
• What characterizes condensation polymerisation monomers?

  Two functional groups
• What usually happens when monomers react during condensation polymerisation?

  Losing small molecules

  
• What is required of a single monomer for condensation polymerisation to occur?

  Two functional groups which can react
• What type of polymer is formed from the condensation polymerisation of a monomer with hydroxyl and carboxyl functional groups?

  Polyester

  
• What two monomers are needed to make a polyester chain?

  Alcohol and carboxylic acid monomers

  
• What functional group is at each end of the alcohol monomer used to create a polyester chain?

  –OH group
• What functional group is at each end of the carboxylic acid monomer used to create a polyester chain?

  –COOH group
• What type of links are formed when monomers link together to polymerise into a polyester?

  Ester links
• What two functional groups do amino acids have?

  Amine and carboxyl
• What are the chemical formulas for the amine and carboxyl groups?

  –NH2 and –COOH

  
• What molecule is given off for each ester link formed in a polyester chain?

  A water molecule
• What type of polymerisation do amino acids undergo to produce polypeptides?

  Condensation polymerisation
• What is condensation polymerisation?

  • Involves monomers with two functional groups
  • Monomers react and join together
  • Usually loses small molecules (e.g. water, HCl)
• What do you need to make a polyester chain?

  • Alcohol monomer with –OH group at each end
  • Carboxylic acid monomer with –COOH group at each end
  • Monomers link together as they polymerise
  • Polymerise by ‘ester links’
  • Water molecule is given off for each link
