Synthetic polymers are human-made polymers that consist of repeated structural units known as monomers. They are versatile materials that can be processed into biomedical foams with a wide range of mechanical, thermal, and degradation properties. Synthetic polymers are mostly non-biodegradable and often synthesized from petroleum oil/Chapter_31%3A_Synthetic_Polymers). Some examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Synthetic polymers are produced in different types of reactions, and many simple hydrocarbons, such as ethylene and propylene, can be transformed into polymers by adding one monomer. Other addition polymers include polybutadiene, polyisoprene, and polychloroprene, which are all important in the manufacture of synthetic rubbers. Synthetic polymers are used in various applications such as packaging, labelling, stationery, textiles, plastics, and in reusable containers, laboratory equipment, etc. . Due to the environmental issues created by these synthetic polymers, which are mostly non-biodegradable and often synthesized from petroleum, alternatives like bioplastics are also being considered.
