Abstract
The well-known LLDPE, LDPE, HDPE modified by (gamma)-ray preirradiation graft method was utilized in this invention for generating the carboxylic group for incorporating with metal ion, resulting an olefin selective membrane for olefin/paraffin separation. These matrices generate free radicals after preirradiation and the grafting reaction was induced with the grafting monomers of unsaturated carboxylic group, the carboxylic group contained grafting polymer was then obtained in this invention. The acrylic acid monomer grafted membrane could incorporated with silver ion by complexation. The reversible complexation between the silver ion and olefin was utilized in olefin/paraffin separation and this silver ion contained complex membrane was an olefin concentrating material. The metal ion solution contained metal ion, hydroxy solvent and oxidation reagent. The metal ion i.e. group V, VI and VII for complex membrane preparation can supply the (pi) electron or monoelectric pair for coordinating. The metal used was Ag, Cu and Rb. The metal salt for complexation must solute in hydroxy solvent. The hydroxyl solvent for metal ion in this invention is the glycerol that the number of hydroxyl group is lower than 4. The oxidation agent could retard the redox reaction of the metal ion and the stability of long term uses could be enhanced. The silver ion contained complex membrane can be a separation material for olefin/paraffin separation via facilitated transport.
