    摘要: SULFUR-CONTAINING POLYEPOXIDES OF THE FORMULA ((R)N-X(+)(-R1))-O-SO2(-)-O-R2 WHEREIN EACH R1 IS A MONOVALENT SUBSTITUTED OR UNSUBSTITUTED HYDROCARBON RADICAL; X IS EITHER NITROGEN, PHOSPHOROUS OR SULFUR; N IS AN INTEGER HAVING THE VALUE EQUAL TO THE VALENCE OF X; AND R IS A MONOVALENT SUBSTITUTED OR UNSUBSTITUTED HYDROCARBON RADICAL CONTAINING AT LEAST ONE OXIRANE OXYGEN ATOM. THE COMPOUNDS OF THIS INVENTION ARE USED TO IMPART CREASE RESISTANCE TO COTTON BASED FABRICS, WET STRENGTH IMPROVERS FOR PAPER AND IN ADDITION THE POLYEPOXIDES PRODUCE THERMOSET POLYMERS.
