I need to construct various glass apparatus fopr anionic polymerization. I couldn't find any texts through scifinder and google please help.
I precipitated the polymer in methanol and then tried to filter the polymer. However, my polymer stuck to whatman filter paper. how can I obtain the polymer now?
