polymers

Question 1

what is a polymer?

Answer 1

is a chemical compound with molecules bonded together in long, repeating chains

Question 2

what is the structure of a polymer?

Answer 2

each polymer molecule is made up smaller units of monomers

Question 3

characteristics of polymers?

Answer 3

• there are intermolecular forces of attraction between polymers molecules
• high surface area, a lot of intermolecular forces, so a lot of energy is needed to break these forces
• high melting point

Question 4

what is polymerisation?

Answer 4

is the process in which the small monomer units join together to form a large polymer molecule

Question 5

what is a monomer?

Answer 5

a molecule that can be bonded to other identical molecules to form a polymer

Question 6

what is a repeating unit?

Answer 6

recurring unit of a polymer

Question 7

what bonds do polymers have?

Answer 7

single carbon. covalent bonds. means they are strong

Question 8

what is an addition polymer?

Answer 8

is the type of polymerisation reaction that occurs when you take the monomers and add them together

Question 9

what is condensation polymerisation?

Answer 9

for this to take place there must be 2 different monomers. each monomer has to have at least two of the same functional group

Question 10

what is the difference between monomers and polymer?

Answer 10

monomers join via carbon-carbon double bond whereas in polymers there is only a single bond
