I'm trying to make a case for purifying a set of polymers using published extraction methods. The polymers I'm interested in have similar physicochemical properties to what has been published, but the published polymers are much higher molecular weight (around 100 kDa), compared to what I'm interested in (10-20 kDa).

I've done some fairly extensive searching, but haven't had any luck yet. I'm just looking for any citations that (hopefully) provide support of polymer molecular weight not having a huge impact on extractability or solubility in a given organic solvent. The polymer types I'd be most interested in would be similar to PNIPAM, PEG, or PLA.

Thanks!
