Synthesis and characterization of hypercrosslinked polymer : effect of reaction time

Hypercrosslinked polymers were categorized as one of the new generation of the porous polymers. The interest in hypercrosslinked polymer is growing rapidly due to their unique physical, chemical and potential applications in many fields from drug-delivery to coatings. In this research, non-aqueous d...
