Abstract

A new method for producing polymeric permeable membranes isdescribed. It is based on inducing chemical decomposition in molecularly dispersed molecules compatible with the polymer which forms the membrane. Decomposition products, which are small molecules, either leave the polymeric matrix, forming pores, or are trapped, and thus may provide for affecting transport through chemical interactions. In this first article the concept is described and illustrated by using polysulfone (PS) as the polymer and di-N-boc-diaminohexane [(CH33COC:ONH(CH2)6NHC:OOC(CH3)3, DBDAH] as the porogen. Possible effects of various parameters are analysed.
