Q: “What are the characteristic of natural polymers?” Natural polymers are produced and formed naturally through polymerization of small simple molecules. Some commonly produced polymers which we use day to day are Polyethylene (a mass-produced plastic which we use in packaging) or Nylon Fibers (commonly used in our clothes, fishing nets etc.) Natural polymers These polymers are found in nature generally from plants and animals sources.

Natural Polymers . Cellulose, another natural polymer, is the main structural component of plants. The penultimate group of chapters reviews the use of natural-based polymers as delivery systems for drugs, hormones, enzymes and growth factors. Chicken nuggets and hamburgers have a lot of protein (but the bun has a lot of starch!).
Synthetic Polymers: Most synthetic polymers are hard to degrade naturally by biological processes. The most common natural polymers are presented below. Synthetic polymers are polymers which humans can artificially create/synthesize in a lab. To add one more main natural polymer is cellulose which is used to prepare lot of things from papers to films etc In addition to these important to life polymers, natural polymers derived from plants and animals have been used by humans for many centuries. 0000001701 00000 n
