Title: Polymers
1Polymers
- Build a molecule of ethane, ethene and ethyne.
- Build a molecule of butane and then build an
isomer of butane (isobutane).
2Polymers
- Carbon-based compounds
- INFER
- How does JELLO (a carbon-based compound) become a
solid? - How does your body produce hair, muscle and skin?
- How can they make a solid plastic out of liquid
petroleum, or rubber out of liquid sap?
3MOLECULES OF LIFE
We are all CBLFs (carbon-based life forms)
- CARBON CAN FORM AN INCREDIBLE VARIETY OF
MOLECULES!!!
4BASIC STRUCTURAL FEATURES A. MULTIPLE BONDS
- SINGLE BONDS -ane
- DOUBLE BONDS - ene
- TRIPLE BONDS -yne
5B. STRAIGHT OR BRANCHED CHAINS
C. ISOMERS
6D. RINGS - Aromatics
Each corner represents a carbon atom. Ring size
can vary from three to eight.
7POLYMERS
Polyethylene
- Carbon atoms can bond to one another in chains to
form a variety of structures, including fossil
fuels such as coal, synthetic polymers such as
plastics, and the large molecules of life, such
as proteins and lipids.
Lipid
Molecular structure of Coal
8All of this allows Carbon to create GIANT
MOLECULES called POLYMERS 100s to 1000s of
smaller molecules joined together. Polymers ARE
CHAINS OF Monomers joined together.

polymer
10POLYMERS (the whole train) are made out of
MONOMERS (individual cars of the train) joined
together.
11POLYMERS (Macromolecules)
12Carbon Polymers - Journal
- Define polymer. Define monomer.
- Name the 3 main types of polymers and give an
example of each - Draw the structural formula for the monomer
ethylene and part of the structural formula for
the polymer polyethylene - Define polymerization
- What is a Catalyst? (use your resources)
13Polymers
- Polymerization When carbon molecules combine
into long chains. - HOW This happens when a carbon to carbon double
bond in a monomer is broken and new single bonds
are formed creating a polymer.

14Polymers
- Polymerization of polypropylene (propene).
15Polymers
- Polymerization (of polyethylene)
16Polymers
- Polymerization (of nylon)
17Polymers
- Living organisms form biopolymers such as
carbohydrates, proteins, lipids and nucleic acids
through polymerization.
18POLYMERS
- FOUR TYPES OF ORGANIC POLYMERS
- CARBOHYDRATES glucose, bread, pasta
- CARBO(C) HYDRATE(H2O)
- PROTEINS muscle, meat, hair, nails
- LIPIDS fat, oil, butter
- NUCLEIC ACIDS DNA, RNA
gtALL CONTAIN C, H, AND O gtCC BONDS ? ORGANIC
COMPOUNDS
19Polymers Proteins
- Polymerization of a protein putting simple
monomers together.
20Polymers Proteins
- Polymerization of a protein putting simple
monomers together. - Where will the monomers JOIN TOGETHER?

22Polymers Proteins
- Polymerization of a protein putting simple
monomers together. - Water drops out to allow the bonds to form.
23Polymers Proteins
- Polymerization of a protein putting simple
monomers together.
24Polymers
- NOT ALL REACTIONS CAN GO BY THEMSELVES.
- Catalyst A chemical substance that STARTS or
INCREASES the rate of a reaction without being
used in the polymer.

25Polymers
- Catalyst A chemical substance that increases the
rate of a reaction without being consumed.
26Carbon Polymers - Review
- Carbon atoms bonded to one another in chains
- 3 TYPES fossil fuels, synthetic polymers, and
biopolymers - Formed through a process called polymerization
- Catalyst STARTS or INCREASES the rate of the
reaction without being used up
27Carbon Polymers - Journal
- Come in
- Have a seat
- Silently read the article from the back
28Carbon Polymers - Journal
- Write down the name, and some of the properties
of the plastic on your desk. - Quick draw an image of both the monomer and
polymer of ethylene. - Re-Read the Polymer Lab Sheet from the back of
the room. - Choose which test (tensile, abrasion, puncture)
that you would want to run, and begin filling out
the back of the sheet.
