Polyurethane structure design for pervaporation membranes
Polyurethane structure design for pervaporation membranes
- ournal of Membrane Science, 61, p.65-72, 1991 .
Polyurea-polyurethane membranes were prepared from polymers with three isocynate terminal groups and molecular weights ranging from 3000 to 6000. Data on pervaporation of ethyl alcohol/ water mixtures were obtained for all the prepared membranes. The permeate fluxes increase with the increasing value of the prepolymers molecular weight.
