    Alternierende copolymerisation mit lewissäuren. Copolymerisation von p-chlorstyrol und n-butylmethacrylat mit ethylaluminiumsesquichloridVortrag anläßlich der Tagung der Fachgruppe “Makromolekulare Chemie” der Gesellschaft Deutscher Chemiker über “Neue Polymere-Spezielle Eigenschaften-Moderne Technologien” in Bad Nauheim am 14. und 15.

    Description / Table of Contents: After a survey of the present knowledge of the alternating copolymerization with Lewis acids the copolymerization of p-chlorostyrene and n-butyl methacrylate with ethylaluminium sesquichloride in homogeneous toluene solution is investigated (copolymerization diagram, composition of the copolymers as a function of the conversion and of the polymerization temperature, dependence of the intrinsic viscosities on the polymerization time, conversion-time-diagram). The 1H NMR spectrum of a copolymer with approximately equimolar composition confirms the alternating structure and the possibility of a mixture of an equimolar copolymer and a homopolymer is ruled out.
    Notes: Nach einem Überblick über die alternierende Copolymerisation mit Lewissäuren wird die Copolymerisation von p-Chlorstyrol und n-Butylmethacrylat mit Ethylaluminiumsesquichlorid in Toluol untersucht (Copolymerisationsdiagramm, Zusammensetzung der Copolymeren als Funktion des Umsatzes und der Polymerisationstemperatur, Abhängigkeit der Grenzviskositäten von der Polymerisationszeit, Zeit-Umsatz-Diagramm). Das 1H-NMR-Spektrum eines annähernd äquimolaren Copolymeren bestätigt die alternierende Struktur und schließt die Möglichkeit einer Mischung aus äquimolaren Co- und Homopolymeren aus.

    Miscibility diagrams of random copolymer blend systems (1992)

    Notes: The miscibility of copolymers AxB1-x and AyB1-y, derived from the same monomer pair (A, B) but differing in composition, was studied. The systems (A, B) were (S, MMA), (BMA, MMA), (S, BMA), and (CIS, BMA) (S: styrene, CIS: p-chlorostyrene, MMA: methylmethacrylate, BMA: n-butylmethacrylate). Miscibility diagrams were recorded, at low and high temperatures, using cast films and dry films. All blend systems feature hightemperature miscibility gaps. Unusual effects of the compositions x and y on miscibility in blends AxB1-x/AyB1-y were observed. The classical prediction that miscibility should depend only on the composition difference |x - y| usually is too simple. It appears necessary to consider dyad interactions.
