초록
Chloromethylation of crosslinked polystyrene resin matrix has been carried out in various organic solvents such as dichloroethane, tetrachloroethane, nitrobenzone, and cyclohexane. The results obtained are as follows. 1. Dichloroethane is a universal solvent in chloromethylation, which is independent on crosslinking agent being used and density of polystyrene. 2. Tetrachloroethane and nitrobenzene acted exclusively on EGD, BDD-crosslinked polystyrene particularly effective for highly crosslinked matrix (8%, 12% crosslinking). 3. In the case of nitrobenzene which has high dielectric constant(
