Polyether and polythioether formation in lactam solvents

Abstract

Abstract POLYMERIC COMPOUNDS OF THE FORMULA -X1-AR1-(Y1-AR1)N1-X2-(AR2-Y2)N2-AR2WHEREIN X1 AND X2 ARE INDEPENDENTLY EITHER OXYGEN OR SULPHUR, AR1 AND AR2 ARE THE SAME OR DIFFERENT AROMATIC RADICALS,N1 AND N2 ARE INDEPENDENTLY OF ONE ANOTHER THE NUMBERS 0-2, AND Y1 AND Y2 ARE INDEPENDENTLY OF ONE ANOTHER A SIMPLE BOND OR A DIVALENT RADICALS, PARTICULARLY ONE OF THE SERIES -O-, -CONH-, -S-, -SO2-, -CO-, -CH2-, -C(CH3)2-, -N=N-, IN WHICH EACH AR IS ATTACHED TO ADJCENT RING MEMBER BY TWO CARBON ATOMS WHICH ARE NOT ADJACENT ONE ANOTHER, AND IS CHARACTERIZED IN THAT AT LEAST ONE COMPOUND OF THE FORMULA: H-X1-AR1-(Y1-AR1)N1-X2-H IS TREATED WITH AT LEAST ONE COMPOUND OF THE FORMULLA: HAL-(AR2-Y2)N2-AR2-HAL IN WHICH HAL REPRESENTS HALOGEN, PARTICULARLY CHLORINE OR BROMINE, AND X1, X2 AND AR1, AR2, N1, N2, Y1 AND Y2 HAVE THE SIGNIFICANCE STATED IN FORMULA I, IN THE PRESENCE OF THE QUANTITY NECESSARY FOR NEUTRALIZATION OF HYDROGEN-HALIDE IN PARTICULAR 1-20% BY WEIGHT EXCESS CALCULATED ON THE STARTING MATERIAL OF AN INORGANIC OR ORGANIC BASE AS ACID ACCEPTOR, IN A SOLVENT OF THE FORMULA: A-N<(-CO-(CH2)M-) IN WHICH A IS AN ALKYL RADICAL WITH 1-4 CARBON ATOMS AND M REPESENTS THE NUMBERS 5-11, AND IN WHICH THE HYDROGEN ATOMS OF THE METHYLENE GROUPS CAN BE WHOLLY OR PARTIALLY SUBSTITUTED BY ALKYL GROUPS WITH 1-4 CARBON ATOMS AT ATMOSPHERIC PRESSURE AT A TEMPERATURE OF 180-200* C
