addition polymerisation

Question 1

define a polymer

Answer 1

a large molecule made of monomer units bonded together

Question 2

what are the two types of polymers

Answer 2

-homopolymer
-copolymer

Question 3

define a homopolymer

Answer 3

a polymer made up of only one type of monomer bonded together

Question 4

define a copolymer

Answer 4

a polymer made up of two or more different types of monomer bonded together

Question 5

how are polymers formed

Answer 5

via a reaction called addition polymerisation(can also be formed via condensation polymerisation but we cover that later)

Question 6

define addition polymerisation

Answer 6

unsaturated monomers bond together to form a polymer by repeatedly adding across the C=C bond, the pi bond breaks but the sigma bond is intact(C-C)

Question 7

what type of polymer is poly(propene)

Answer 7

a homopolymer

Question 8

draw the repeating unit of poly(propene)

Question 9

what does n stand for on a repeating unit

Answer 9

the number of repeating monomer units in the polymer chain

Question 10

can copolymers be represented like this

Answer 10

yes, search up an example and they may use different letters for each unit like x, y and z
