I have a question on the alkylation of polystyrene. I carried out a reaction using the the friedel crafts condition to alkylate polystyrene. But unluckily the reaction do not proceed. (same NMR spectrum as the starting material). Here are the reactants and conditions I tried:
Solvent: THF (anhydrous)
I tried polystyrene to bromodecane ratio = 1:1 and 1:2, while using 10% catalyst at 85 degrees and 120degrees celsius. But still no luck to see any alkylation in NMR. I am not sure if I should add more catalyst. If so, How do I remove them during the work-up procedure??
Any help or suggestions will be greatly appreciated! Thank you!
