Abstract:
New PIM-1 copolymers with 2,3,6,7-anthracenetetrayl moiety have been synthesized as fine powders from 2,3,6,7-tetrahydroxy-9,10-di(p-fluorophenyl)anthracene monomer in DMSO, with crystal structure of the monomer as well as its precursors and the product of its model side crosslinking reaction being determined using X-ray diffraction. The microporosity and surface characteristics of the copolymers powders have been measured. As-cast membrane from the copolymer with 5 mol% of the monomer synthesized revealed promising gas separation properties as compared with original PIM-1.
