摘要
Networked, crosslinked poly[(2-hydroxyethyl methacrylate)-co-(ethylene glycol dimethacrylate)] (HEMA-EGDM) was synthesized by frontal polymerization (FP) using azobisisobutyronitrile as initiator. HEMA-EGDM copolymers of similar composition were also synthesized by suspension polymerization. The two sets of copolymers were characterized for functional groups (IR), pore volume (mercury intrusion porosimetry), surface area (nitrogen adsorption) and morphology (scanning electron microscopy). FP-generated polymeric network structures had higher internal pore volumes and surface areas but their surface morphologies were inferior to those of copolymers synthesized by suspension polymerization.
