Question

Why alkenes dont undergo condensation polymerization?

Answer 1

BECAUSE ALKENE NOT GIVE SMALL MOLECULES AS A BYPRODUCT so...

Answer 2

Explanation:

Hey !!

Question :- Define

(1) Addition polymers

(2) Condensation polymer

Answer = Addition Polymer = The addition polymers are formed by the repeated addition of same or different monomer molecules. The monomers used are unsaturated compounds.

Example :- Alkenes , Alkadienes

Polythene is an example of addition polymer.

     

     nCH₂ (Double Bond) CH₂ --333 - 343 K, 6 - 7 atm ( Ziegler - Natta Catalyst ) -----> ( CH₂ --- CH₂ )n

NOTE :-  nCH₂ (Double Bond) CH₂  ( ETHENE )

( CH₂ --- CH₂ )n ( HIGH DENSITY POLYTHENE )

CONDENSATION POLYMER

The condensation polymers are formed by the repeated condensation reaction between different bifunctional or trifunctional monomer units usually with elimination of small molecules such as water , alcohol , hydrogen chloride, etc.

Example :- Nylon - 6 , Nylon - 6 , 6 and terylene.
