    Notes: Oriented polymeric membranes were originally prepared by polymerization or polycondensation of preoriented monomers. The introduction of hydrophilic spacer groups into the polymeric amphiphiles allowed the formation of highly ordered systems (monolayers, liposomes, multilayers) from prepolymerized amphiphiles: due to the partial decoupling of the different mobilities and orientation tendencies of the polymer chain and the amphiphilic side groups, these polymers are able to self-organize. In monolayer experiments the high order of these membranes could be demonstrated by their surface pressure area-diagrams. In addition the combination of order and mobility of these spacer groups containing polymeric amphiphiles allowed the formation of Langmuir-Blodgett-multilyers with a high layer correlation. Thus, disturbancies in highly oriented layers can be avoided normally taking place during the polymerization reaction (e.g. contractions) or oriented monomeric layers.

    Description / Table of Contents: A method is described for determining the phase separation point of highly concentrated LDPE solutions by measuring the cloud point temperature. The relationship between cloud temperature and size of the resulting PE particles obtained in various solvent systems is discussed.
    Notes: Eine Methode zur Bestimmung des Entmischungspunktes von höherkonzentrierten LDPE-Lösungen durch Ermittlung der Trübungstemperatur wird beschrieben. Der Zusammenhang zwischen Trübungstemperatur und Größe der resultierenden PE-Teilchen aus verschiedenen Lösersystemen wird diskutiert.
