Semi-synthetic polymers These polymers are obtained from natural polymers by simple chemical treatment to change the physical properties of natural polymers like Starch, silicones. Industrial or synthetic polymers are a product of the oil industry. 2. However, the majority of polymers or plastics used for engineering design are synthetic and often they are specifically formulated or “designed” by chemists or chemical engineers to serve a specific purpose. 0000014280 00000 n
The penultimate group of chapters reviews the use of natural-based polymers as delivery systems for drugs, hormones, enzymes and growth factors. Natural polymers such as starch, xanthan or guar gum, carrageenan, alginates, polysaccharides, pectin, gelatin, agar, and cellulose derivatives can be used for this purpose. Natural polymers include proteins, DNA, RNA, starch, glycogen, etc. These are commercially produced by industries for human necessities. Polymers can also be classified based on the type of monomers present in them. %%EOF
