  1. Polymers (9.3) By: Joey Coughlin & Madison Jeffers

  2. Polymers • A polymers is a larger molecule that forms when many smaller molecules are linked together by covalent bonds. • Poly means “many.” • DNA is a type of polymer.

  3. Types of Polymers

  4. Synthetic Polymers • Synthetic polymers are is an industrial produced chemical substances consisting of a number of molecules together with covalent bonds. (Exp. Plastics, rubber, nylon, and polyethylene.)

  5. Rubber • Supply of natural rubber is limited because of how much we use it. • We make rubber because supplies are low. • Rubber is copolymers (polymers consisting of more than one monomer)

  6. Natural Polymers • Natural polymers are made by living things (not humans), plants, animals, ect… (Exp. Sugar molecules are linked together in chains.)

  7. Sugar Molecules • Sugar molecules have actually been found in the gas around a young sung like star! • Sugar molecules are the most common natural polymers.

  8. Vulcanized rubber • In the 1800’s Charles Goodyear came up with a plan to make rubber more heat resistant. He succeeded with a rubber called Vulcanized Rubber.

  9. Nucleic Acids • Nucleic acids are large neutron containing polymers found in the nuclei of cells. There are two types. DNA,RNA

  10. DNA • Two Strands of DNA line up in sequence. DNA looks like a rungs of a ladder. There held together by strong molecular attractions between hydrogen atoms on one side and nitrogen or oxygen on the other.

  11. Polymer Quiz • 1) What are polymers? • 2) What are two types of polymers? • 3) What type of polymer is rubber? • 4)Who came up with a way to make rubber more heat resistant. (Hint: Last name type of tire.) • 5) What are two nucleic acids? (Hint: Learned about them last year.) • 6) Where have scientist recently found sugar molecules that is surprising? • 7) What type of polymer is sugar molecules? • 8) What is Vulcanized rubber? • 9) Why do we make rubber? • 10) What are copolymers?

  12. Answers • 1) A larger molecule that forms when many smaller molecules are linked together by covalent bonds. • 2) Natural and synthetic • 3) Synthetic • 4) CharelesGoodyea • 5) DNA RNA • 6) Gas surrounding a sun like star • 7) Natural • 8) A rubber that is more heat resistant • 9) Because rubber is limited and we use it for tires, ect.. • 10) Polymers consisting of more than one monomer
