Cellulose, chitin, pectin, and proteins are examples of natural polymers. Table 9.1 presents different types of polymers and their sources (Fig. 9.3). Table 9.1. Different natural polymers with their source of origin. S. No.Natural polymerSources 1 Cellulose Cell walls of plants 2 Collagen ...
Polymers are very common in nature; some of the most widespread naturally occurring substances are polymers. Starch and cellulose are examples. Green plants have the ability to take the simple sugar known as glucose and make very long chains containing many glucose units. These long chains are ...

A further application linked to the clays can be their use as geopolymers, inorganic polymers, similar to natural rocks, produced by geosynthesis and utilised to obtain ceramic materials. Geosynthesis consists of polymerization by condensation (geopolymerization) of base molecules originating from natura...
Materials which provide such enhancement include extrudable thermoplastic polymers (TPU's) or extrudable thermoplastic elastomers (TPE's) which exhibit a combination of a low Young's modules (E) and a low Poisson's ratio (σ). The Poisson's ration is preferably below 0.5, which is the ...
The coating process modifies the raw material by adding hydrophobic reagents or polymers to get a hydrophobic surface. Examples are shown in U.S. Pat. No. 4,519,918, U.S. Pat. No. 4,925,343, U.S. Pat. No. 5,021,390, U.S. Pat. No. 5,492,881 and U.S. Pat. No. 5,891...
Examples of naturally occurring polymers include silk, wool, deoxyribonucleic acid (DNA), cellulose and proteins. These polymers have been widely applied in many industry areas, such as foods, textiles, papers, woods, adhesives, and pharmacies. Some natural polymers, such as gelatin, alginate, ...
