Dear sir

We the 3rd year students of b. Sc polymer chemistry studying in mes kvm college, valanchery wrote pc 6b 01 polymer chemistry -1 paper on 28th march, 2019.

This is to bring into your attention that the following questions asked in the exam paper of pc 6b 01 polymer chemistry -1 (Question paper code - c 60075) were out of the syllabus:

Part b :

1) what is meant by compounding? (2marks)
2) what are fillers? Give examples. (2 marks)
3) what is fatigue? (2 marks)
4) what are engineering plastics? (2 marks)
5) what are high temperature polymers? (2marks)

Part c:

1) discuss effect of copolymerisation on mechanical properties? (6 marks)
2) differentiate between tear, wear and abrasion resistance. (6 marks)
3) discuss cryoscopic method for molecular determination. (6 marks)
4) how will you use tga to study polymer degradation? (6 marks)

Part d:

1) explain gpc technique in polymer characterisation. (10 marks)
2) explain light scattering. (10marks)
3) derive expression for kinetics of stepwise polymerisation. (10 marks)

Kindly take the required action for ensuring justice and future wellbeing of students.

Yours sincerely
