    Notes: [Auszug] In November 1960, a report from Perth, Western Australia, suggested that larvae feeding in manure heaps was resistant to a * shotgun mixture' of DDT, 'Dieldrin' and 'Diazinon' following 3 years successful control. Shortly after, a report was received that 'Diazinon' was losing efficiency in ...

    Arylsulfonic polymers. II. Synthesis and polymerization of fluorosulfonylaryl monomers (1960)

    Notes: Owing to the stability of the sulfonyl fluoride group and the reactivity of the amino group, aminobenzenesulfonyl fluorides enable the synthesis of a large number of polymers and copolymers bearing sulfonic acid groups. It is indeed possible to react aminobenzenesulfonyl fluorides with acrylic or methacrylic acid chloride or with vinyl isocyanate to obtain substituted acrylamides or vinylureas which can be polymerized or copolymerized with other vinyl monomers. Another method of preparing arylsulfonic polymers with the use of aminobenzenesulfonyl fluorides is the reaction of the latter with polymers containing reactive groups, such as polyacrylic anhydride and copolymers of maleic anhydride. The fluorosulfonyl-substituted polymers and copolymers can easily be hydrolyzed in slightly alkaline medium.

    Description / Table of Contents: Vinyl-trans-cinnamat, ein asymmetrisches Divinylmonomeres, wurde synthetisiert und aus ihm ein lineares lösliches Polymeres hergestellt.Mit Hilfe von Infrarotspektren sowie auf chemischem Wege konnte gezeigt werden, daß diese Polymeren sich von einem Polyvinylcinnamat, das durch Veresterung von Polyvinylalkohol mit Zimtsäurechlorid erhalten wurde, wesentlich unterscheiden.Die Polymeren, die durch Polymerisation des Monomern erhalten wurden, sind durch die Anwesenheit von γ-Lacton-Ringen, die infolge eines Cyclopolymerisationsmechanismus entstanden, gekennzeichnet.
    Notes: Vinyl trans-cinnamate, an unsymmetrical divinyl monomer, has been synthesized, and polymerized to linear, soluble polymers.It was found by infrared and chemical analysis that these polymers are quite different from polyvinyl cinnamates synthesized through esterification of polyvinyl alcohol by cinnamoyl chloride.The polymers prepared by polymerization of the monomer are characterized by the presence of γ-lactone rings resulting from a cyclopolymerization mechanism.
