โœฆ Synopsis

Membranes were dynamically formed of pofy(glutamic acid) and poiy (acrylic acid), and their byperfiltration (reverse osmosis) properties investigated.

Rejections

were high in comparison wirh those of organic pofyelectrolytes previously studied. Rejection properties of cast (cross-linked) films were similar. Transmission rates through cast poly@utamic acid) fifms were much lower than through those dynamically formed of the same polyelectrolyte, in accord with our usual experience. Cast polyacrylate membranes, however, had extremely high permeation rates for films having comparable rejection made of any material; fluxes were in many cases higher than those of polyacrylate membranes formed dynamically.

A novel semi-interpenetrating polymer network (semi-IPN) membrane composed of crosslinked chitosan(cr-CS) and poly(acrylic acid) (PAA) was prepared. Evidence from infrared spectra proved the formation of polyelectrolyte complex through electrostatic interaction between NH / 3 groups from CS and COO
