USES OF POLYMERS IN INDUSTRYZach Johnston

VARIETY OF POLYMERS Widely present throughout the world Mostly used in homes, the industry, and

sports activities

NYLON Discovered shortly before WWII Prepared from coal, air, and water Replaced silk as the form of stockings and in

parachutes

POLYESTER Thermoplastic polymer

-Contains the Ester Group (C-CO-O-C) Polyethylene terephthalate (PET)

-Can be spun into threads and woven into cloth

Used in the manufacturing of plastic bottles and films

POLYCARBONATES Sub-group of thermoplastic polyesters Contains C-O-CO-O-C Some are very durable and more transparent

than glassOther uses are for CD’s and DVD’s

KEVLAR Polyamide Polymer Contains the amide group C-CO-NH-C Five times stronger than steel on a weight

basis Used as a reinforcement for boat hulls,

airplanes, and bicycles, along with the manufacturing of body armour.

POLYVINYL CHLORIDE Polymer that is widely used in the building

industry. Used for the manufacturing of gutters and

down pipes Hard and relatively brittle thermoplastic

material

THE USES OF BIOMEDICAL POLYMERS IN THE BIOMEDICAL FIELD

HIGH POLYMERSHigh polymers are used for

medicine, sugary, or artificial organs in three separate ways:

A: Construct artificial organsB: Repair/Sustain human organsC: Provide a Biomedical Function

HIGH POLYMERS (CONT)Examples of Biomedical Polymer

inventions include: Artificial Hearts, Heart-Lung machines, Artificial Kidneys.

HIGH POLYMERS (CONT) Plastics have properties that are beneficial

for these inventions to work Including non-toxic properties, physical

properties such as flexibility, hardness. Plastic mostly used in Biomedical polymers

as surgical implants are: polytetrafluoroethylene, polypropylene, saturated aromatic polyesters, and polysiloxanes.

SMART POLYMERS Found in living organisms (carbohydrates,

proteins) Used for their predictable behavior for drug

delivery Non-linear response makes them unique in

that they change once, and then continue to behave in the changed way

SMART POLYMERS (CONT.) Mainly used in drug deliveries (timed-release

pharmaceuticals) Scientists have created a way for the Smart

Polymer to control the release of the drug until they reach the target site, controlled by either a chemical or physiological behavior.

SMART POLYMER (CONT.) Smart Polymers have given way to Polymers

such as: polyanhydrides, polyesters, polyacrylic acids, poly(methyl methacrylates), and polyurethanes

WHAT ARE POLYMERS

Polymers are giant molecules with molar masses ranging from thousands to millions. They are found everywhere and are in things we use daily. They range from synthetic polymers like polyester to organic polymers such as the nucleotides in DNA. Mainly, any substance with the word poly in it, is a polymer.

POLYMERS IN FOOD Starch is a polymer, it is made up of glucose,

where as glucose is a monomer. There are also polymers found in the shells

of crustaceans such as lobsters, this is because most proteins are polymers.

POLYMERS IN OUR BODIES Cellulose is also a polymer, its found through

out our lives. First, its in trees and in paper, but it is also now seen as a somewhat health risk or flaw in humans because our bodies don’t produce enzymes to make them glucose monomers.

POLYMERS IN DAILY PRODUCTS

Polymers are found every where in our daily lives, from the lotions we use on our hands such as the glycerin (C3H8O3) in Alveeno, or the synthetic rubber in tires. You can also find polymers in toothpaste, Carbopol, a registered polymer, is found in many house hold materials.

POLYMERS IN CLOTHING In clothing, you find polymers in about any

piece of clothing if it isn't 100% fabric, this is because, polyester, a main thread in fabric is a polymer. It is a durable material that has become popular in a world where we try to reduce the cost of clothing.
