Modified question (2015-09-18):
Here I have an oxidation system (all of them are just micromolecular reagents), and I planned to use this system to oxidize some kinds of biopolymers which containing alcohols group. It has proved by many papers that this oxidation system could finish the similar oxidation with some aromatic alcohols and fatty alcohols in a very high yield, such as 90%. However, when I apply this system to these biopolymers, the yield of oxidation shown quite low, sometimes 2%. I am writing this question to ask some ideas to help me improve the yield or efficiency of oxidation.
All of the micromolecular reagents in this oxidation system could dissolve in the reaction solvent. The biopolymers are hard to dissolve in the solvent or need harsh condition, but could disperse well in the solvent. I had tried my reaction condition to increase the conversion ratio, including the temperature, pH, concentration of reactant, reaction time and even adding reactant in steps, but the conversion ratio still has no obvious increasing. The highest one got is no more than 10%. Too harsh reaction was out of the condition in our lab, and it is not the goal for me.
I am not sure this time, I gave a relative clear description of my question and request?

Original question (2015-09-17):
The reaction between a specified oxidant and the monomer (or the similar reagent containing the same group) could get a quite high yield, even 100%, but the oxidant cannot oxidize the corresponding polymer in a high yield, some time just 1%.
How could improve the yield when apply this oxidant in the polymer?
Thank you!
