    Notes: Summary Rotation possibilities and rotational barriers in polyesters from 3,3-bis(chloromethyl)oxetane and dipotassium isophthalate were evidenced. Based on the obtained data it was presumed that every repeating unit behavies as a mesogenic, confering liquid-crystalline properties to the polyester.

    Description / Table of Contents: The synthesis of statistical copolyamides of aliphatic and aromatic type with various proportions of cycloaliphatic monomers (trans-cyclopropane dicarboxylic acid) is presented. For the obtained products the thermal, solubility and structural properties were determined. The results showed that the presence of cycloaliphatic units in the copolyamide chain have a very similar influence on the polymer properties as aromatic monomers.
    Notes: Die Synthese statistischer Copolyamide von aliphatischen und aromatischen Typ mit unterschiedlichen Anteilen cycloaliphatischer Monomere (trans-Cyclopropandicarboxylsäure) wird beschrieben. Die erhaltenen Produkte wurden hinsichtlich ihrer Struktur und der thermischen Eigenschaften analysiert. Die Ergebnisse zeigen, daß die Einführung cycloaliphatischer Einheiten auf die Eigenschaften der Polymere eine ähnliche Wirkung hat wie aromatische Monomere.

    Description / Table of Contents: Die Zusammenhänge zwischen der Art der inerten Trägermatrix, den experimentellen Kopplungsbedingungen und den Eigenschaften des Enzym-Matrix-Komplexes werden untersucht. Die Ergebnisse zeigen, daß die Hydrophilie des Trägers für die Kopplungsreaktionen von wesentlicher Bedeutung ist.
    Notes: An experimental investigation was performed to correlate the kind of carrier with experimental coupling conditions and properties of the final enzyme-matrix complex. The obtained results suggest that hydrophilicity of the carriers plays in important role in coupling reactions.

    Description / Table of Contents: Die Möglichkeiten einer Synthese von Polyethern mit Oxetanseitengruppen aus 3,3′-bis(Chlormethyl)oxacyclobutan und Bisphenol-A wurden untersucht. Die Reaktionen wurden entweder bei hoher Temperatur in Gegenwart von K2CO3 in Lösung oder durch Grenzflächenkatalyse unter verschiedenen experimentellen Bedingungen durchgeführt. Die Struktur der synthetisierten Produkte wurde durch IR- und NMR-Spektroskopie charakterisiert. Die Polymere wiesen eine gute thermische Stabilität auf. Durch Öffiien des Oxetanrings mit stark elektrophilen Reagenzien können sie vernetzt merden.
    Notes: The possibility of producing polyethers with pendant oxetane groups from 3,3′-bis(chloromethyl)oxacyclobutane and bisphenol-A was investigated. Reactions were carried out at high temperature in presence of K2CO3 in N,N-dimethyl acetamide solution or by using phase transfer catalysis under various experimental conditions. The structure of the synthesized products was characterized by IR and NMR spectroscopy. The polymers show high thermal stability. They were crosslinked by opening of the oxetane ring with powerful electrophile agents.

    Description / Table of Contents: Aromatisch-cycloaliphatische Polyester wurden ausgehend von aromatischen Diolen und cycloaliphatischen C-3 und C-4 Chloranhydriden durch Phasengrenzenpolykondensation synthetisiert. Die Polymere wurden IR-spektroskopisch und thermogravimetrisch charakterisiert. Hinsichtlich des thermischen Verhaltens sind diese Produkte zwischen vollaromatischen und aliphatisch-aromatischen Polyestern einzureihen.
    Notes: Polyesters of aromatic-cycloaliphatic type were synthesized by interfacial polycondensation from aromatic diols and C-3 and C-4 cycloaliphatic chloroanhydrides. The polymers were characterized by i.r. spectroscopy and thermogravimetry. Their thermal properties showed that these products range generally between fully aromatic and aliphaticaromatic polyesters.
