It is a presentation about polymers in our daily life.

3. Synthetic polymers are produced by chemical
reactions, termed "polymerizations." Polymerizations
occur in varied forms--far too many to examine here--
but such reactions consist of the repetitive chemical
bonding of individual molecules, or monomers.
Assorted combinations of heat, pressure and
catalysis alter the chemical bonds that hold
monomers together, causing them to bond with one
another. Most often, they do so in a linear fashion,
creating chains of monomers called polymers.

4. Polystyrene (PS) is a
synthetic aromatic polymer made from
the monomer styrene. Polystyrene can be
solid or foamed.

5. Polyethylene terephthalate , commonly known
as PET, PETE is the most
common thermoplastic polymer resin of
the polyester family and is used in fibers for
clothing, containers for liquids and
foods, thermoforming for manufacturing, and in
combination with glass fiber for engineering resins.

6. Polyvinyl chloride commonly abbreviated PVC, is
the third-most widely produced
synthetic plastic polymer,
after polyethylene and polypropylene.
Polyvinyl chloride is produced by polymerization of
the vinyl chloride monomer .

7. Polybutylene succinate (PBS) is
a thermoplastic polymer resin of the polyester
family.
PBS is a biodegradable aliphatic polyester with
properties that are comparable to polypropylene.

8. 1.IN MEDICINE Many biomaterials, especially heart
valve replacements and blood vessels, are made of
polymers like Dacron, Teflon and polyurethane.

9. 2.IN SPORTS
Playground equipment, various balls,
golf clubs, swimming pools, and
protective helmets are often produced
from polymers.

10. 3.IN SCIENCE
Plastic containers of all shapes and
sizes are light weight and
economically less expensive than
the more traditional containers.
Clothing, floor coverings, garbage
disposal bags, and packaging are
other polymer applications.

11. 4.IN INDUSTRY
Automobile parts, windshields for fighter
planes, Pipes, tanks, packing materials,
insulation, wood substitutes, adhesives,
matrix for composites, and elastomers
are all polymer applications used in the
industrial market.
