✦ Synopsis

A series of new 4,4 -(1,4-phenylene)dipyrimidines 5a-c, 8a-c, and 10a,b have been synthesized from the reaction of amidines 1a-c with the dienaminone 2, bis-chalcone 6, or ylidenemalononitrile 9. The reaction of malononitrile and ethyl cyanoacetate with 2 gave 6,6 -(1,4-phenylene)di(pyridin-2(1H)-ones) (15a,b). The structures of the products were proved by elemental analyses,

Poly(2,6-dimethyl-1,4 -phenylene oxide) (PPO) is a chemically resistant polymer and, therefore, an attractive material for the formation of membranes. However, membranes of unmodified PPO prepared by an immersion precipitation possess very low hydraulic permeabilities at the filtration processes. T
