Lab 3-Polymers

Question 1

Aim

Answer 1

To synthesize a polymer and observe its properties

Question 2

Polymers

Answer 2

Are found in nature and are artificially prepared

Question 3

Synthetic polymers

Answer 3

Are solids with diverse useful physical properties

Question 4

Polymers are…

Answer 4

Long chains of identical molecules linked together by strong chemical bonds

Question 5

Monomers to polymers

Answer 5

They form covalent bonds to link together and form the polymer

Question 6

Addition polymerization

Answer 6

Monomers that contain multiple bonds may be linked together

Question 7

End of a polymer

Answer 7

Is capped by a hydrogen or some other atom

Question 8

Condensation polymerization

Answer 8

Two molecules join together and produce a smaller molecule

Question 9

Copolymer

Answer 9

When two different monomers form a polymer

Question 10

First commercial polymer

Answer 10

Nylon 6, 6

Question 11

Polymer chains

Answer 11

Are long, but not linear. They have a flexible back bone.

Question 12

Cross linking

Answer 12

Modifies the flexibility of a polymer. This is the process of connecting the chains by forming covalent bonds. A stiffer material is formed as chains cannot slide past one another

Question 13

Cross linking substance

Answer 13

Sodium borate will be used for polyvinyl alcohols

Question 14

Cross linking kinetics

Answer 14

Are relatively slow

Question 15

PVA

Answer 15

The polymer used to make most plastics

Question 16

Borax and water

Answer 16

Create a borate ion
