Hello students, let's begin with this question.
00:03
Here we have to write down these polymers in the increasing order of the glass transition, glass transition temperature.
00:17
So, now here if we talk about firstly the low density, low density polyethylene, this will have the branched structure and due to this structure, this will have the lower packing efficiency and due to which it will have the lower glass transition temperature.
00:54
This is represented by this tg.
00:57
Then the next one is, next one is the polyvinyl chloride.
01:05
So, this polyvinyl chloride, this will contains the chlorine which is a, which is a polar atom and which leads to, this makes the stronger intermolecular, stronger intermolecular forces and it will has a high glass transition temperature.
01:41
Now here the next one is the polystyrene.
01:47
So, here this polystyrene, this will have a phenyl ring.
01:53
Due to this ring, this will, this will be restricted rotation and due to this restriction, this will have a high glass transition temperature.
02:13
Now the next one is the natural rubber...
