Separation of isopropyl alcohol–water mixtures by pervaporation using crosslink IPN membranes
Polyvinyl alcohol (PVOH) has been chemically modified by crosslink copolymerization of
acrylic acid (AA) and hydroxyethylmethacrylate (HEMA) in aqueous solution of PVOH and
finally crosslinking PVOH to produce a full interpenetrating network (IPN) membrane termed
as PVAH. Accordingly, three such full crosslink IPNs, ie PVAHI, PVAHII and PVAHIII
containing varied weight ratio of PVOH and copolymer along with crosslink PVOH (which
has not been modified by copolymerization) have been synthesized and used for …
