Abstract
Multicomponent networks or membranes of the present invention have good mechanical properties that are permeable to water, hydrocarbons, and oxygen. The networks contain at least two and preferably at least three covalently combined domains, i.e., a hydrophilic, a lipophilic and an oxyphilic polymer segment, that give rise to a multicontinuous domain microstructure. At least one of these domains includes poly(ethylene glycol).
