cloud point

[Leroy]

i know this is actually polymer chemistry, but there is no seperate forum for that and i thought that organic was the closest related to it.

 

What i was wondering is how you can determine average molar mass of a polymer through simple titration. I have heard of cloud point but can anyone tell me what i would need to do exactly to determine the average molar mass through this method??

Cloud point is temperature of the system where a pahse separation can occur so you have a solvent polymer interface or you get polymer formed and it looks cloudy. The point where acloud point occurs gives you separation of the polymer so that by collecting this polymer and running a GPC you could get number average molecular weight and avaerage molecular weight.
