Описание слайда:
Polymerization
Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers.

Science
Polymers are studied in the fields of biophysics and macromolecular science, and polymer science (which includes polymer chemistry and polymer physics).
Слайд 6
Описание слайда:
Types of
Polymers are two types:
- Natural polymeric materials such as shellac, amber, wool, silk and natural rubber have been used for centuries.
- Synthetic polymers that includes synthetic rubber, phenol formaldehyde resin (or Bakelite), polyethylene, polypropylene, po-lyacrylonitrile, PVB, silicone, and many more.
