An oxygen scavenging composition that can be either thermoplastic or thermoset, and that comprises at least one oxygen scavenging polymer and at least one curing agent is disclosed. The oxygen scavenging polymer comprises a polymeric backbone, at least two curing functional groups that are terminal
An oxygen scavenging composition that can be either thermoplastic or thermoset, and that comprises at least one oxygen scavenging polymer and at least one curing agent is disclosed. The oxygen scavenging polymer comprises a polymeric backbone, at least two curing functional groups that are terminal groups and at least one oxygen scavenging cyclic moiety having from 5 to 9 carbon atoms in its ring and at least one carbon-carbon double bond in its ring. The curing functional groups of the oxygen scavenging polymer can be independently selected from hydroxyl groups, amino groups, carboxylic groups, sulfonic groups, and epoxy groups. The curing agent comprises at least two functional groups that are capable of reacting with the curing functional groups of the oxygen scavenging polymer.

A method of forming a pattern according to claim 1, wherein the fourth step involves a step of dry-etching the anti-reflective coating with a sulfur-containing etching gas and by using as a mack the pattern of radiation-sensitive material coating to form a pattern of the anti-reflective coating and then dry-etching the etchable layer using as a mask the pattern of the radiation sensitive material coating and the anti-reflective coating to form a pattern of the etchable layer. 3. The method of forming a pattern according to claim 2, where the etching gas comprises sulfur dioxide and oxygen. 4. The method of forming a pattern according to claim 1, where the onium salt is selected from a sulfonium salt, a iodonium salt, a phosphonium salt, a diazonium salt, and a pyrdinium salt. 5. The method of forming a pattern according to claim 1, where the sulfone compound is selected from bissulfonylmethane, bissulfonyidiazomethane, sulfonylcarbonyidiazomethane, and sulfonylcarbonylalkane. th claim 16, wherein a front end of said heater is brought into contact with a bottom surface of said inside chamber formed by an inside surface of said opposed closed end of said solid electrolytic element. 22. The air-fuel ratio sensor in accordance with claim 16, wherein said metallic holder is made of a metallic plate, and each of said heater holding portion and said fixing portion is formed into an open cylindrical shape with a slit by bending said metallic plate so as to have a C-shaped ring cross section along a plane normal to said axial direction. 23. The air-fuel ratio sensor in accordance with claim 22, wherein each slit of said heater holding portion and said fixing portion is aligned on a same axial line. 24. The air-fuel ratio sensor in accordance with claim 16, wherein said heater holding portion and said fixing portion are integrally connected via a connecting portion. 25. The air-fuel ratio sensor in accordance with claim 24, wherein said connecting portion is a neck portion narrower than said heater holding portion and said fixing portion. 26. The air-fuel ratio sensor in accordance with claim 16, wherein said heater has a rectangular cross section. 27. The air-fuel ratio sensor in accordance with claim 16, wherein said heater has a through hole extending in the axial direction. 28. The air-fuel ratio sensor in accordance with claim 16, wherein said fixing portion of said metallic holder is elastically expandable in radially outward directions so that said fixing portion is engaged with the inside surface of said solid electrolytic element by a resilient force caused by said fixing portion. 29. The air-fuel ratio sensor in accordance with claim 16, wherein said fixing portion of said metallic holder is elastically expandable in radially inward directions so that said fixing portion is engaged with the outsi
