Polymer

Poly means many and mer means unit. Polymer means many unit of monomer.

Example: (-CH₂-CH₂-)_n

Here n=10000-100000

Basic classification of polymer:

1. On the basis of origin:
1. Natural (Cotton, wool).
2. Synthetic (PVC, Nylon, PVA).
2. On the basis of chemical structure:
1. Organic (PVC, PVA).
2. Inorganic (Glass, rubber).
3. On the basis of thermal behavior:
1. Thermoplastic (PVC, PET, Nylon).
2. Thermoset (MF Resin, Bakelite).
4. On the basis of linear structure:
1. Chain structure.
2. Branched.
3. Network polymer (Bakelite).
5. On the basis of composition:
1. Copolymer.
2. Homo polymer.
6. On the basis of form and uses:
1. Plastic (PVC).
2. Elastomer (Silicon, rubber).
3. Fibers (Nylon, Polyester).
4. Liquid resin (Polysurphide sealants).
