[PDF] condensation polymerization vs addition

Addition polymerisation is the process of repeated addition of monomers that possess double or triple bonds to form polymers. Condensation polymerisation is a process that involves repeated condensation reactions between two different bi-functional or tri-functional monomers.

  • Why are condensation polymers stronger than addition?

    Since there are few branches in condensation polymers, they are usually linear and can thus pack closely tegether.
    Condensation polymers are therefore more rigid than addition polymers and have a higher tensile strength.

  • What is the difference between condensation polymerization and copolymerization?

    The difference between condensation polymerisation and copolymerisation is that in condensation polymerisation, small molecules like water, HCl are eliminated when the reaction between two functional group containing monomers takes place.
    But in copolymerisation it is not definite that elimination will take place.

  • What is additional polymer or condensation polymers?

    Addition polymers are formed of chains of carbon atoms with strong C-H bonds and are resistant to biodegradation.
    Condensation polymers are formed by the elimination of water or other small molecules from two or more reactant monomers.

  • What is additional polymer or condensation polymers?

    In a step-growth reaction, the growing chains can react with each other to form longer chains.
    This holds true for chains of all lengths.
    But in an addition polymerization, only the monomers can react with growing chains.
    Two growing chains can't join together the way they can in a step-growth polymerization.
