Abstract

Ring-opening addition reactions between pentaerythritol tetra(oxiran-2-ylmethyl) ether [pentaerythritol polyglycidyl ether (PPE)] and polyethylenepolyamine, i.e., ethylenediamine (EDA), diethylenetriamine (DETA), triethylenetetramine (TETA), and tetraethylenepantamine (TEPA), have been investigated to yield network polymers. The reactions in ethanol under the equivalent molar ratio of epoxy and NH groups, [epoxy]/[NH] = 1.0 mol/mol, at 60 ºC successfully yielded porous polymers. The surface morphology of the porous polymers showed connected particles with the diameters ranged from bout 5 μm to 20 μm. The monomer concentration and molecular structure of the polyethylenepolyamine compound affected the particle size in the porous polymers. All the porous polymers were sufficiently soft and flexible to be unbroken under 40 N of compression. The porous polymers absorbed various solvents and showed high water permeability. The porous polymers adsorbed an anionic dye selectively. Surface treatment of a porous polymer by alkali aq. made it possible to adsorb a cationic dye.

期刊介绍： Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including: polymer synthesis; polymer reactions; polymerization kinetics; polymer physics; morphology; structure-property relationships; polymer analysis and characterization; physical and mechanical properties; electrical and optical properties; polymer processing and rheology; application of polymers; supramolecular science of polymers; polymer composites.
