Polymer chemistry-Polydispersity index
« on: February 11, 2021, 06:42:47 AM »
Hello,

I have a problem with the polydispersity index. It sounds like that: Which is the polydispersity index of a telechelic oligomer with the number average degree of polycondensation equal to 10, obtained by the polycondensation of a hydroxy acid? I tried to solve it like that:/

Xn=1/(1-p)=10 -->p=0.9

Xw/Xn=1+p --> Xw=19

PDI=Xw/Xn=19/10=1.9

Can you tell me please if it is correct or I have to do something else? Thank you! ;D
