Question

What are the melting temperature (Tm) and glass transition temperature (Tg) of a polymer?

What should be the values of those temperatures of a good polymer and how we can we improve them​

Answer 1

Answer:

1) glass-rubber transition temperature (Tg) 2) crystalline melting temperature (Tm) - can be correlated with the chemical structure by means of a method based on group contributions. Tg (glass transition temp ) – the onset of segmental motion of the polymer backbone.
