Mechanism of hypercrosslinking of chloromethylated styrene–divinylbenzene copolymers

摘要: Abstract Hypercrosslinked polymers are remarkable materials exhibiting extremely high apparent surface area and exceptional sorption properties. Their special morphology is a result of the fixation expanded position polymer chains in good (swelling) solvent by methylene crosslinking bridges created Friedel–Crafts reaction chloromethyl groups. We have performed detailed investigation formation starting from swollen, already chloromethylated polymer. Conversion groups was determined residual chlorine content. The total content after burning sample oxygen reactive, accessible with pyridine were differentiated. Changes both types monitored for varying conditions (time, catalyst content, etc.) correlated development microporous texture resulting hypercrosslinking swollen matrix.
