Introduction to Monomers and Polymers in Chemistry

WebbMonomers are simple molecules and the smallest repeating units in polymers. Polymers are very large molecules ( macromolecules) that are made from single repeating units (monomers). There are three categories of monomers: monosaccharides, amino … WebbThese polymers can be thermoplastic or thermosetting. Although all plastics are in a liquid state at some point in processing and are solid in the finished state, once a thermoset polymer is formed, it cannot be melted and reformed. The monomers in a polymer may be arranged in a variety of ways.
