    Notes: A series of poly(2-hydroxyethyl methacrylate)/polyamine graft copolymers (HA copolymers) were examined as an adsorbent for cellular adsorption chromatography in order to separate cell populations with high efficacy. The capability of each copolymer sample to selectively adsorb rat lymphocyte subpopulations (B-cells and T-cells) was evaluated by applying a lymphocyte suspension to a copolymer-coated glass bead column. A separation factor (AB/AT) greater than 5.0 was achieved for the HA copolymer, compared to 1.9 and 1.1 for homopolymers of poly(2-hydroxyethyl methacrylate) and of a polyamine (poly(N,N-diethylaminoethylstyrene)), respectively. By loading a rat lymphocyte suspension containing B-cells (28%) and T-cells (72%) through the HA copolymer column, more than 60% of T-cells in 90% purity or more were recovered in the effluent.

    Description / Table of Contents: Quecksilberdichlorid polymerisiert Diketen bei tiefer Temperatur. Das Molekulargewicht der in Aceton unlöslichen und in Dioxan löslichen Fraktion des Polymeren war 1630.Die Untersuchung der Reaktionsprodukte der Alkoholyse des Polymeren und die Infrarotspektren zeigten, daß das Polymere die Struktur eines offenen Vinylaceto-β-lactons hatte. Es ist daher anzunehmen, daß auch Diketen die Struktur eines Vinylaceto-β-lactons hat, obwohl die fünf starken Banden im Doppelbindungsgebiet noch unbestimmt bleiben.
    Notes: Mercuric chloride polymerized diketene at low temperature. The molecular weight of the acetone-insoluble and dioxane-soluble fraction of the polymer was 1630.From the alcoholysis of the polymer and the infrared spectrum of the polymer, the molecular structure of the polymer was considered to be the open chain polymer of vinylaceto-β-lactone. Consequently, the molecular structure of diketene was also believed to be vinylaceto-β-lactone, although the assignments of the five strong bands in the doublebond region still remain in question.

    Description / Table of Contents: Die Reaktionsprodukte von Lithiumaluminiumhydrid und Crotonsäureestern unter Polymerisationsbedingungen wurden gaschromatographisch analysiert. Die Reaktivitätsverhältnisse von C—C-Doppelbindungs- zu Carbonyl-Addition des Hydrid-Ions gegenüber Methyl-, iso-Propyl- und sec-Butyl-Crotonaten wurden bestimmt zu 3:1, 20:1, 9:1 und 40:1. Das Zwischenprodukt der Doppelbindungs-Addition wurde als Vorläufer der Polymerisation bestätigt. Die Vorläufer unterliegen danach einer Carbonyl-Addition an das Monomere und beenden so das Wachstum bei Reaktion mit dem Methyl- und dem iso-Butylester; im Falle von iso-Propyl- und sec-Butylester ergab die Doppelbindungs-Addition Hochpolymere. Das Reaktionsprodukt von Methylcrotonat und LiAIH4 zeigte gute katalytische Wirkung bei der Polymerisation von Crotonaten.
    Notes: The reaction products of lithium aluminum hydride with crotonic esters under polymerization conditions were analyzed by gas chromatography. The ratios of carbon-carbon double bond- to carbonyl-addition of the hydride ion toward methyl, iso-propyl, iso-butyl and sec-butyl crotonates are determined as 3:1, 20:1, 9:1, and 40:1, respectively. The intermediate double bond addition product was confirmed to be a precursor of the polymerization. The precursors undergo successive carbonyl-addition onto monomer, terminating the propagation rapidly in the reactions with methyl and isobutyl esters; in case of iso-propyl and sec-butyl esters double bond additions yielded high polymers. The reaction product of methyl crotonate and lithium aluminum hydride showed good catalytic activity for polymerization of crotonates.
