|
What happens to the double bond in an alkene during polymerisation?
it remains unchanged
it opens up, allowing monomers to join
it breaks completely
it becomes a triple bond
|
What is the smallest section of a polymer chain that repeats over and over called?
backbone
repeating unit
monomer
plasticiser
|
What is the correct name for the addition polymer made from propene?
poly(propene)
polymer(propane)
polymer(propene)
poly(propane)
|
Why are most plastics non-biodegradable?
due to their reactive structure
due to their unreactive structure
due to the presence of plasticisers
due to their polar nature
|
Which of the following is NOT a viable approach to dealing with plastic waste?
incineration
recycling
landfilling
using biodegradable polymers
|
What is a potential issue with burning plastic waste?
it may produce toxic emissions
it increases the flexibility of the plastic
it makes the plastic more reactive
it produces no heat for electricity generation
|
The individual alkene molecules that join together to form a polymer are called .
|
What is the term for the process of joining many monomers together to form a polymer?
|
polymers contain light-sensitive carbonyl groups (C=O) that absorb energy from UV light, leading to the weakening and breaking of nearby bonds.
|
What is the term for the process by which polyamides and polyesters can break down?
|
List three advantages and three disadvantages of recycling polymers.
|
In polyesters, the links (-COO-) are broken down through acid hydrolysis into alcohols and carboxylic acids.
