What are the advantages and disadvantages of addition polymerisation?

Answer 1

Disadvantages -

- Use up a nonrenewable/finite resource

- take a long time to decompose

- take up space in landfill

- cause pollution in oceans

- produce poisonous gases on combustion

Advantages -

- can form any shape

- they don't corrode

- cheaper than alternative materials

- less dense so lighter

- good insulator of heat ( home insulation )

- good insulator of electricity ( wire covers )

- wind power is impossible without plastics ( Special plastics are used in the wind turbine covers and huge blades to tap into this environmentally friendly energy source! )

- The amount of fuel a delivery truck needs could be considerably reduced if the cargo uses plastic containers? Obvious: lightweight means less fuel consumption!

Hope this helps :-)

Answer 2

Addition polymerizations are usually carried out in bulk and solution polymerization.

Advantages and disadvantages of Bulk polymerization

ADVANTAGES

• The system is simple and requires thermal insulation.
• The polymer is obtained pure.
• Large castings may be prepared directly.
• Molecular weight distribution can be easily changed with the use of a chain transfer agent.

DISADVANTAGES

• Heat transfer and mixing become difficult as the viscosity of reaction mass increases.
• The problem of heat transfer is compounded by the highly exothermic nature of free radical addition polymerization.
• The polymerization is obtained with a broad molecular weight distribution due to the high viscosity and lack of good heat transfer.
• Very low molecular weights are obtained.

Advantages and Disadvantages of solution polymerization

ADVANTAGES

· Manipulation of polymerization conditions is relatively simple.

· Additives can easily be used and there is a broad range of design possibilities. (Various properties can be achieved.)

Thin film coating is possible.

DISADVANTAGES

· Uses organic solvents.

· Requires the use of solvent recovery equipment.

Difficult to use at high concentrations.

Answer 3

Advantages:

1. High molecular weight polymers can be produced efficiently.
2. Can be used to create a wide range of polymer types with different properties, such as polyethylene and polypropylene.

Disadvantages:

1. Can be wasteful if uncontrolled, leading to byproducts and impurities.
2. Requires specific conditions and catalysts, which can be costly.
