In line with the further thriving demand for downstream derivatives of allyl alcohol, cumene and vinyl acetate monomer worldwide, Chang Chun Group decide to expand the operation of allyl alcohol, cumene and vinyl acetate monomer in Singapore.
4. What are monomers and polymers? In organic chemistry, a monomer is a molecule by itself. Monomer means âa single partâ. Some examples of organic monomers are a glucose molecule, a nucleotide, or an amino acid. Polymers are macromolecules built of two or more monomers. Polymer means âmany partsâ. Polymers are often long chains of monomers. For example, starch is a polymer. It is a long chain of glucose molecules. Proteins are polymers composed of chains of amino acids. DNA is a super- long polymer of nucleotides. Even small macromolecules like a dipeptide (two amino acids joined together) are polymers. 5. Explain the chemical reaction for building a polymer from a set of monomers.
