The influence of the synthesis parameters on poly(acrylonitrile-co-dim
ethacrylate esters) copolymers of gel, or porous type structures, has
been studied. The porous beads possess good mechanical strength, low s
pecific surface area (S < 20.0 m(2)/g), good apparent densities (d(ap)
= 0.4000-0.5000 g/mL), and consequently very large pores. (C) 1997 El
