In this unit, we are creating polymer. So, what is Polymers? Polymers are large molecules that are chemically bonded together. They can be separated into many different parts, and each separated part is called a monomer. Monomers are small molecules that are joined together. Now, to be specific there are two types of polymers. Artificial and natural. Artificial polymers are often identical and is made by scientists and engineers. For example nylon, polyester, plastic and more. The manufacturing of artificial polymer is difficult, I will use acrylic fiber as an example. First polymerisation happens, it means combining two sets of molecules, and changing it into a different structure. Then, heating and spinning, workers would heat the polymer. After a while, air causes polymer to harden, at last fibres are are stretched to create strength. On the other hand, natural polymers are the opposite, their links are different from the bond next to them. They are naturally found and can be extracted. A few examples of natural polymers are silk, wool, DNA and more. But one thing bad about natural polymer is if we used it all we can’t find any more materials to replace it. So we should use environmentally products, and help save our planet earth.
