Question

The low density polythene LDP obtained through free radical addition and H atom abstraction has highly branched structure.

Can you please make me explain :- what last line H- atom abstraction...... Structure, Mean with branching I couldn't link it with branching.

Answer 1

Here,
Free-radical addition is an addition reaction in organic chemistry involving free radicals. The addition may occur between a radical and a non-radical, or between two radicals.

Abstraction means Removal of an atom or group from a molecule by a radical. Hydrogen atom abstraction removal of hydrogen atom from the molecule by the radical.

LDP obtained as highly branched structure due to above mentioned proccess.
