Polymers and its types in chemistry

1. INTRODUCTION TO POLYMERS

3. POLYMER
 A polymer is define as the substance having very
high molecular weight and is made by joining of
large number of simple molecules .
 These are the molecules having certain structural
unit repeating large number of times .

4. TYPES OF POLYMERS
 Natural Polymers
 Synthetic Polymers
 Linear Polymers
 Commercial Polymers

5. COMMERCIAL POLYMERS :
 Poly Ethylene
 Poly Propylene
 Poly Vinyl Chloride
 Poly Vinyl Acetate
 Poly Styrene
 Poly Acrylonitrile
 TEFLON

6. POLY VINYL CHLORIDE{PVC} :
 Polyvinyl Chloride is obtained by heating a water-emulsion of
vinyl chloride in presence of a small amount of benzyl peroxide.
 PVC is generally prepared by treating acetylene at 1 to 1.5 atm
with hydrogen chloride at 60-80 degree.

7. PROPERTIES :
 PVC is colourless odourless,non-
inflammable and resistant light,inorganic
acids and alkalis.
 Pure resin possesses a high softening
point and a greater stifness and rigidity
compared to polyethylene, but is brittle.
 It is the mostly widely used in synthetic
plastic.

8. USES OF PVC :
 PVC is mainly used in PVC pipes.
 It is used in making sheets, light-fittings,
refrigerator parts.
 It is also used in cycles, tyres, motor cycle
parts, toys, aero-planes parts.

9. APPLICATIONS OF POLYMERS
 It is difficult to find an
aspect of our lives that is
not affected by polymers.
 Polymers in daily life.
 Polymers in sports.
 Polymers in medicine.
 Polymers in aero-space.
 Polymers in electroincs.
 Polymers in defence.

10. Top Polymer Companies:
 Dow, Dupont, Basf, Bayer, Mitsubishi.
 Mercedes-benz, Audi, Maruti.
 SABIC, Shell, Braskem, Ticona.
 PPG Industries and Eastman.
