Hello students, in this video we will study about polymers.
00:02
So, when polymers solidify from a melt or a solution, they can form crystalline structures.
00:06
They are formed in two ways.
00:08
So, the first one is nothing but chain folded, folded.
00:15
And the second one that we have is nothing but extended chain form, extended chain form, chain form.
00:26
Alright, it's the two in form.
00:28
So, the first one that we have is that is entropy, entropy.
00:34
So, in the case of entropy in the extended, extended chain form, chain form, we know that results in, results in lower entropy state, lower entropy state.
00:59
Alright, and now the second point that we have is kinetics, kinetics.
01:09
So, the process of crystallization, the process of crystallization, involves the, involves the nucleation, nucleation and growth of crystalline regions and growth of crystalline, crystalline regions, regions...
