Abstract: The invention provides microporous polymer films which comprise a halopolymer in which the repeat units are -(C n H 2n )- and -(C m X 2m )-, where each X independently represents fluorine or chlorine and the values of n and m are more than one and less than six. The films of the invention can be suitable for use in high temperature applications and can be substantially inert to certain chemically aggressive substances such as alkali and alkaline earth metals. The films find particular application in electrochemical cells comprising a lithium anode and thionyl chloride electrolyte.

Abstract: The present invention provides a resinous porous article having a high interconnected hole porosity and capable of retaining a large amount of a lubricating oil and does not rust iron and steel, even though an unextracted portion of a pore-forming substance bleeds out when the resinous porous article is used as parts which contact a metal portion or the like and a method of producing the resinous porous article. The resinous porous article is formed by a producing method of molding a resin containing the pore-forming substance into a molding, and extracting the pore-forming substance from the molding with a solvent which does not dissolve the resin therein. The resinous porous article has an interconnected hole porosity not less than 30%. The pore-forming substance consists of an alkali compound.
