WebCategories of polymers. Based on the nature of the repeat units, polymers can be-Homopolymer; Copolymer; Homopolymer. The polymers in which repeating units are from only one monomer unit are known as homopolymers. The Molecular weight of the polymer is higher since it has numerous monomers. This process is a step-growth polymer.
