Nanoporous polymers with permanent porous structure and high surface areas of up to 2084m2/g have been prepared via hypercrosslinking of polystyrene copolymers using Friedel-Crafts alkylation reaction. The hypercrosslinked polymers were prepared in two formats, continuous “monolithic” blocks, and beads. Optimization of the preparation process and hypercrosslinking conditions enabled generation of...
Hypercrosslinked polymers containing functionalized alternating copolymer sequences of substituted stilbene or styrene and N-aryl substituted maleimides have been synthesized. Alternating copolymers containing these comonomers possess semi-rigid structures, and incorporation of these units into the precursor polymer particles for hypercrosslinking leads to a systematic increase in T g and...
