    摘要: Method for converting pendant functional groups, particularly upon perfluorocarbon copolymeric cationic exchange materials, to sulfonyl fluoride pendant functional groups. The method comprises a catalyzed reaction between the perfluorocarbon functional group and SF.sub.4 under pressure at relatively mild reaction temperatures.

    摘要: The invention provides a lubricating composition containing an oil of lubricating viscosity and a block copolymer. The block copolymer may contain (a) a hydrophobic first block having C1-30 alkyl (meth)acrylic units, wherein at least 50 wt % of the C1-30 alkyl (meth)acrylic units are C12-15 alkyl (meth)acrylic units, and up to 50 wt % of the C1-30 alkyl (meth)acrylic units are C16 20 alkyl (meth)acrylic units, with the proviso that alkyl groups of the C1-30 alkyl (meth)acrylic units have an average total number of carbon atoms of at least 8; and (b) a second block having (meth)acrylic units further having a heteroatom-containing group providing a polar group. The invention further relates to a method of lubricating an internal combustion engine by lubricating the engine with the lubricating composition. The invention further relates to the use of the block copolymer as an emulsifier and/or pour point depressant.

    摘要: A method for making a quite finely divided particulate copolymeric perfluorocarbon having pendant cation exchange functional groups, and having an equivalent weight of at least in excess of 900 but not greater than about 1500. In the method, the perfluorocarbon copolymer is solvated in a solvent and then precipitated from solution by addition of a substance miscible in the solvent but having essentially no capability for solvating the perfluorocarbon copolymer. The method is conducted at a temperature generally below about 300.degree. C.
