摘要
The invention provides novel polymer conjugates that are especially useful in the separation of carboxylic acids from complex fermentation compositions. The polymer conjugates comprise polyethylene glycols or oxides and polyethyleneimine or polypropyleneimine in various ratios. The novel polymer conjugates permit enhanced extraction of carboxylic acids from fermentation systems not only through their use in partitioning the carboxylic acids from various polymeric components of the fermentation system, but also through their use in adjusting the pH of the system for optimal performance and separation.
