    摘要: A surface of aluminiferous metal is brought into contact at 30 DEG C to 65 DEG C for 5 to 60 seconds with a surface treatment bath with a pH of 2.0 to 6.5 that contains phosphate ion, condensed phosphate ion, and a water soluble polymer in the following weight proportions: 1 - 30 : 0.1 - 10 : 0.2 - 20. This is followed by a water rinse and drying by heating. The water soluble polymer has a chemical structure conforming with formula (I), in which (i) each of X and X represents a hydrogen atom, a C1 to C5 alkyl group, or a C1 to C5 hydroxyalkyl group; (ii) each of Y and Y represents a hydrogen atom or a moiety "Z" that conforms to formula (II) or (III), wherein each of R , R , R , R , and R represents a C1 to C10 alkyl group or a C1 to C10 hydroxyalkyl group; (iii) the average value for the number of Z moieties substituted on each phenyl ring in the polymer molecule is from 0.2 to 1.0; (iv) n is an integer with a value from 2 to 50; and (v) each polymer molecule contains at least one Z moiety.

    摘要: Verfahren zur Herstellung von methylsubstituierten Polyalkylidenpolyphenolen, die in Mischungen mit Kautschuk oder als Bindemittel in lichtempfindlichen Massen eingesetzt werden können und erhalten werden, indem gegenüber Oxoverbindungen bifunktionelle und/oder trifunktionelle methylsubstituierte Phenole mit Oxoverbindungen in Gegenwart saurer Katalysatoren in erster Stufe zu einem niedermolekularen Polyalkylidenpolyphenol reagiert werden, wobei das Einsatzmolverhältnis zwischen phenolischer Komponente und Oxoverbindungen zwischen 1 : 0,2 bis 1 : 0,7 liegt, die nicht umgesetzten phenolischen Komponenten anschließend destillativ entfernt werden und in zweiter Stufe das nach der Destillation zurückgebliebene niedermolekulare Polyalkylidenpolyphenol in Gegenwart von sauren oder basischen Katalysatoren mit weiteren Oxoverbindungen umgesetzt wird.

    摘要: A resin composition comprising (A) a polycyanoarylether consisting essentially of the repeating unit represented by the following general formula (I)

    and having a reduced viscosity of at least 0.6 dl/g as measured at 60 °C in p-chlorophenol at a concentration of 0.2 g/dl and (B) a carbonized phenolic resin is suitable for sliding parts of electric and electronic instruments and machines because it exhibits excllent abrasion resistance and reduces the damage to counterparts. The sliding characteristics of the resin composition is further increased by addition of a non-fibrous solid lubricant.
