• Ans: Plastics, fibers, paint and varnishes & elastomers
• 2. What is a Polymer?
• * large molecules
• * high molecular mass(10^3-10^7)
• * (a) Macro molecules:
• @ formed by joining repeating structural units(derived from MONOMERS& connected by co-valent bonds) on a large scale.
• 3. what is polymerization?
• The formation of polymers from respective polymers is known as polymerization.
