so good lecture, way better than my professor taught...he is one of that kind of professors that forgot what students know and do not know because he excels in this field so much for so many years doing advanced research

If I have two polymers, I have two peaks so two aerias, how can I calculate the purity of the two polymers?

sir what is the relation of PET Resin intrinsic viscosity and DSC Tg Tm define please

Very very very clarifying😊

I need a reference book on this sir😊

Nice class

Thank you very much Professor

Sir, can you share the files you have used ?

Sir i have a question that between LCST & UCST which is favourable for getting a polyblends

Why l1*l2 = 0? I cannot understand reason...If there is no corrlation between two vector, the result gonna be zero?

thank you!!

Thanks,Sir

Very helpful video!

you saved my life, i was about to give up - thank you so much 😍

Why did you multiplied the DP with 2 to get the actual number of bonds

Thank you for the lectures Professor Ryu. It was very helpful in understanding the theory behind polymer blends. You mentioned chapter 18 in a book. May I ask which book you are refering to?

very educative. Thank you !

Thank you so much, i want to know about the book

does anyone know the text booK?

hello, does anyone know the reference book for this course?

You are the best

Excellent way to explain DP of Molecular weight

Why not use wavelengths in the UV range.

Zimm graphs confusing... Explain using one type of graph only, plz.

The explanation is perfect! Thank you Professor Ryu!

교수님 안녕하십니까! Rayleigh ratio가 왜 scattering volume과 Io에 independent한지 설명 가능해주실 수 있으신가요?

Well explained

thanks for a nice video. I leant new things about different volume changes as a result of faster or slower cooling rates. However, I still did not understand why a more packed (annealed or aged) polymer would consume more energy than needed (overshooting) when passing to the rubbery-like state....

Fantastic video - helped tons!

Nice one

For asphalt modification, do you prefer a mix of TPE or TPU?

thanks🤩🤩

Oko fresh okay shower

Fantastic. Cheers.

이렇게 좋은 강의를 올려주셔서 감사합니다. From Seoul, Korea.

Nice and simple explanation of basic concepts in polymer. Can you tell the name of the software you are using ?

Thanks for posting such a good video, could you upload the presentation file in ppt of this video?

Professor, is there a way to calculate the statistical segment length of block copolymers?

Can you explain M/ NA ( Avagardo number) ?

dear Dr , pls can you help me in this question if i have a drug and polymer how can i calculate the chi parameter between both can you guide me to which mathmatical way so appreciated advancely

dear Dr is there any software make a simulation on flory-huggins basis for prediction thanks in advance

Can you suggest any book in which this all detailed explanation is mentioned

Thank you Sir for great and detailed explanation!!

Hi.Great video, thank you! I hope you can help me with a quick question. Where do I get the Ci data from? I have my calibration line and my logM but how do I get the Ci from RI? Appreciate it!!!

do we always multiply by 2 for the number of C-C bonds? for any polymer that can be given? Also why dont we consider the third bond (the right one) so we multiply by 3 ?

What if kreamer and huggins equation are pararell - what is error in experiment?

I really appreciate this Prof.'s calm and clear way of explanation!!!

Thank you. Helpful lecture series.

Thank you for posting this lecture.
