4. WHAT ARE THE POLYMER

6. What is the most important monomer?
The most abundant natural monomer is glucose,
which is linked by bonds into the polymers cellulose,
starch, and glycogen.

7. What is polymerization

10. Classification of Polymers
Based On Structure

15. Classification of Polymer

16. Homopolymer & Heteropolymer

17. Free-radical
polymerization (FRP)

19. LDPE (LOW DENSITY
POLYMER)

24. HDPE (high density
polyethylene)

28. PAN

30. TEFLON

32. NYLON 66
Nylon is a synthetic polymer called a polyamide

33. Nylon-6

36. Dacron / terylene

39. ABS polymer structure

46. Why is polymerization
dangerous?
Vigorous polymerization is
potentially hazardous because the
reaction may get out of control. Once
started, the reaction is accelerated by
the heat that it produces. The
uncontrolled buildup of heat and
pressure can cause a fire or an
explosion, or can rupture closed
containers.

48. Biodegradable polymers
special class of polymer that breaks
down after its intended purpose by
bacterial decomposition process to
result in natural byproducts such as
gases (CO2, N2), water, biomass,
and inorganic salts.

49. Biodegradable and non
biodegradable polymers. ...
The polymers which can decompose
in a few days are decomposed by the
action of microorganisms and are
known as Biodegradable Polymers.
The polymers which are not
decomposed by the action of
microorganisms and are referred to
as non-biodegradable polymers.

53. Electrochemical
polymerization
electropolymerization is based on the deposition of
the polymer onto the surface of a solid electrode
material. This occurs through a generally accepted
mechanism that involves the formation of cationic
radical by the oxidation of the monomer on the solid
electrode material.
Electrochemical polymerization of aniline can be
easily conducted on so-called “inert” electrodes, i.e.,
diverse graphite, platinum, gold, indium-tin-oxide
glasses, or carbon. However, as fairly large electrode
potential is a necessity for oxidation of aniline,
consumption of other substances is restricted
