    Notes: The melting, crystallization and dynamic mechanical behaviour of blends of bacterially produced poly[D(-)-3-hydroxybutyrate] (PHB) and poly[D(-)-3-hydroxyvalerate] (PHV) have been investigated. Results showed that melt-pressed PHB-PHV blends contained phase-separated domains in the melt which subsequently crystallized as PHB and PHV type spherulites respectively. The two melting regions detected by DTA related to separate melting of PHB and PHV crystallites, which were almost unaffected by the blend composition. The mechanical behaviour of a random copolymer of PHB/HV was compared with that of a blend of almost the same composition, and found to be markedly different.

    Description / Table of Contents: From the mixture of homologous sodium diamido-imidophosphates obtained by heating sodium diamidophosphate, by means of an anion exchanger in fluoride form and a KF solution as eluant the dimeric, trimeric and tetrameric compounds are isolated in solution. From this the silver salts are precipitated. On re-precipitation at pH 9, they yield silver salts in which the imido hydrogen also is substituted by silver.
    Notes: Aus dem Gemisch homologer Natrium-diamido-imidophosphate NanPnO2n(NH)n-1(NH2)2, das beim Erhitzen von Natriumdiamidophosphat entsteht, werden mit Hilfe eines Anionenaustauschers in Fluoridform und einer KF-Lösung als Eluiermittel die dimere, trimere und tetramere Verbindung in Lösung isoliert. Daraus werden die Silbersalze gefällt, die bei Umfällung bei pH 9 Silbersalze liefern, in denen auch der Imidowasserstoff durch Silber ersetzt ist.
