MSE 201 S21 Lecture 30 - Module 1 - Polymer Thermal Transitions

This video goes over the thermal transitions of polymers like glass-transition temperature, Tg, and melting temperature, Tm.

@Thom Cochell . Thank you for your great explanation on thermal transitions. Is there any references for polypropylene material with transition times?

great

why slow cooling rate brings the tg at lower point however we know that slow cooling allow better growth of crystal, so of course amorphous part will be less.

[@buntekarotte]

I have the same question. Do you now have an answer?

[@pyare45]

@@buntekarotte I think becasue due to slow cooling leads better growth of crystal and small portion of amorphous that why Tg decrease to lower side.
