MACRORETICULAR NITRILIC NETWORKS

The study of the synthesis parameters, applying the suspension techniq ue on poly(acrylonitrile-co-dimethacrylate esters) copolymers of gel, or porous type structures has been performed; The porous samples posse ss a quite good mechanical strength, a low specific surface (S < 20.0 m(2)/g), apparent density (d(ap) congruent to 0.4000-0.5000 g/mL), and consequently very large pores. Toluene was used as porogen compound a nd its quantity influence was investigated, too.
