Question

Write differences between addition and condensation polymers

Answer 1

read in the class 12 chemistry no. 2. its explained very nicely

Answer 2

$\huge\rm{\underline{Answer :-}}$

___________________________________________

$\bold\orange{\underline{Difference : (1)\implies}}$

• Addition polymers :There is no loss of simple molecules during polymerisation of atom
• Condensation polymers : There is loss of simple molecules during polymerisation.

$\bold\red{\underline{Difference : (2)\implies}}$

• Addition polymers : The molecular mass of polymer is an exact multiple of molecular mass of monomer.
• Condensation polymers : The molecular mass of polymer is not an exact multiple of molecular mass of polymer.

$\bold\pink{\underline{Difference : (3)\implies}}$

• Addition polymers : They are formed by the addition of monomers and leave no by-products behind.
• Condensation polymers : They are formed by the condensation of monomers and leave behind by-products like ammonia, water etc.

$\bold\green{\underline{Difference : (4)\implies}}$

• Addition polymers : Examples of addition polymers are : polystyrene, polyethylene, polyacrylates etc.
• Condensation polymers : Examples of condensation polymers are : polyester, polyamide, polyurethane, and polysiloxane.
