18.3.2 Condensation Polymers

    Cards (49)

    • Condensation polymers are polymers that form when monomers react to create a larger polymer and a small molecule, usually water
    • Condensation polymers lose atoms during formation, unlike addition polymers.
    • What is the general reaction formula for condensation polymerization?
      nA+nA +nB(AB)n+ nB \rightarrow (AB)_{n} +nH2O nH_{2}O
    • Match the type of polymerization with its characteristics:
      Condensation ↔️ Monomers react and lose atoms
      Addition ↔️ Monomers add together without losing atoms
    • Condensation polymerization is a process where monomers join together to form a larger polymer molecule, accompanied by the release of a small molecule, typically water
    • Steps in the process of condensation polymerization:
      1️⃣ Monomer Reaction
      2️⃣ Bond Formation
      3️⃣ By-product Release
      4️⃣ Chain Extension
    • Polyamides are formed from the reaction of a diamine and a dicarboxylic acid.
    • What is the by-product of polyamide formation?
      Water
    • Match the aspect with the type of polymerization:
      By-products present ↔️ Condensation
      Monomers directly add together ↔️ Addition
    • Condensation polymers release a small molecule, usually water, during formation.
    • Condensation polymers are formed when monomers react and lose atoms, releasing a small molecule such as water
    • What is the by-product of condensation polymerization?
      Water
    • The general reaction for condensation polymerization is nA + nB \rightarrow (AB)_{n} + nH_{2}O
    • Ordering of the reaction for condensation polymerization:
      1️⃣ Monomers react with reactive functional groups
      2️⃣ A covalent bond forms between the monomers
      3️⃣ A small molecule, usually water, is eliminated
      4️⃣ The process repeats to extend the polymer chain
    • What is the by-product released during the formation of condensation polymers?
      Water
    • Condensation polymers are formed when monomers combine without losing atoms.
      False
    • Condensation polymers release a small molecule, usually water
    • What type of molecule is released during the formation of condensation polymers?
      Small molecule (water)
    • In addition polymerization, monomers combine without losing atoms
    • Match the polymer type with its characteristic:
      Condensation ↔️ Monomers lose atoms
      Addition ↔️ Monomers combine without losing atoms
    • Steps in the condensation polymerization reaction process:
      1️⃣ Monomers with reactive functional groups combine
      2️⃣ A covalent bond forms between the monomers
      3️⃣ A small molecule, such as water, is eliminated
    • Polyamide, like nylon, is formed using diamine and dicarboxylic acid as reactants.
    • The by-product of polyamide formation is water
    • What is the general equation for the formation of polyamides during condensation polymerization?
      n(NH_{2} - R_{1} - NH_{2}) + n(COOH - R_{2} - COOH) \rightarrow [NH - R_{1} - NH - CO - R_{2} - CO]_{n} + 2nH_{2}O</latex>
    • Condensation polymerization requires functional groups on the monomers, while addition polymerization uses unsaturated monomers.
    • Which monomers are used to form polyesters?
      Diol and dicarboxylic acid
    • Polyesters are formed through the esterification
    • The formation of polyesters releases water as a by-product.
    • What is the key difference between condensation and addition polymers in terms of atomic composition?
      Condensation polymers lose atoms
    • Condensation polymers release water during their formation, while addition polymers do not.
    • Condensation polymerization involves the release of a small molecule, typically water
    • What is the resulting polymer when diamine and dicarboxylic acid react in condensation polymerization?
      Polyamide
    • Condensation polymers require functional groups on monomers, while addition polymers use unsaturated monomers.
