Introduction
1.Natural polymers a.These polymers are found in plants and animals. b.Examples are proteins, cellulose, starch, some resins and rubber. 2.Semi-synthetic polymers a.Cellulose derivatives as cellulose acetate (rayon) and cellulose nitrate, etc. are the usual examples of this sub category. 3.Synthetic polymers a.A variety of synthetic polymers as plastic (polythene), synthetic fibers (nylon 6,6) and synthetic rubbers (Buna - S) are examples of man made polymers extensively used in daily life and industry.
