Zur copolymerisation von α‐methylstyrol und butadien III. Das NMR‐spektrum der sequenzen mit zentraler α‐methylstyroleinheit
Authors: Elgert K. F. , Seiler E. , Puschendorf G. , Cantow H.‐J. 
Published: April 2003

AbstractDie 220‐MHz‐Protonenresonanzspektren von Copolymeren aus α‐Methylstyrol und Butadien werden untersucht. Die Modellsubstanzen stellt man in einer durch Lithiumbutyl initiierten Copolymerisation bei −75°C in Tetrahydrofuran dar. Das NMR‐Spektrum der Phenyl‐ und α‐Methylgruppe wird durch die Signale konfigurativer Triaden und Triaden mit zentraler α‐Methylstyroleinheit erklärt. Die chemische Verschiebung der Triaden mit zentraler α‐Methylstyroleinheit erfolgt im α‐Methyl‐Bereich soweit zu niedrigerem Feld, daß keine starke Überlappung mit den Signalen der konfigurativen Triaden auftritt. Im Bereich der Phenylprotonen sind konfigurative Triaden und Triaden mit zentraler α‐Methylstyroleinheit überlagert. Bei Verwendung von 3,4,5‐Trideutero‐α‐methylstyrol ist es möglich, die Zuordnung von konfigurativen Triaden und Triaden mit zentraler α‐Methylstyroleinheit im Spektrum der ortho‐Phenylprotonen zu treffen.
Caractérisation de réactions primaires de dégradation oxydante au cours de l'autoxydation des polyoxyéthylènes à 25°C: Étude en solution aqueuse avee amorçage par radiolyse du solvant. II. Arguments pour un mécanisme monomoléculaire de décomposition des radicaux peroxyles
Authors: Crouzet Claude , Marchal Jean 
Published: April 2003

AbstractDes coupures statistiques sans période d'induction sont observées au cours de I'autoxydation du polyoxyéthylène étudiée dans l'eau 1 25°C et à l'abri de la lumikre. L'homolyse des hydroperoxydes formés sur le polymère ne peut pas expliquer les coupures car elle est trop lente dans ces conditions. La décornposition de radicaux alcoxyles secondaires produits par la réaction bimoltculaire non terminante des radicaux peroxyles formts sur le polymère ne fournit pas non plus l'explication de ces coupures. En effet, pour que les cinttiques théorique et expérimentale de production des coupures soient en bon accord, il faudrait, contrairement aux propriétés connues des radicaux peroxyles secondaires, que la réaction bimoléculaire de terminaison des radicaux peroxyles soit négligeable par rapport à leur réaction bimoléculaire non terminante. Un mode de décomposition des radicaux peroxyles selon un mécanisme monomoléculaire restant à définir doit donc être responsable de la dégradation oxydante ainsi caractérisée.

Authors: Engel F. 
Published: April 2003

AbstractDie durch AIBN initiierte Polymerisation von Methacrylonitril wurde bei 50–75°C in Substanz untersucht. Die Reaktionsordnung ist in bezug auf die Initiatorkonzentration 1/2. Die Bruttoaktivierungsenergie beträgt 22,9 kcal . mol−1. Wird K2w/ka (Kw = Wachstumskonstante, ka = Abbruchskonstante) aus dem Zahlenmittel des Polymerisationsgradaes (P̄n) und der Bruttogeschwindigkeit zur Zeit t = 0 (vbr,0) bestimmt, darf bei Polymeren mit bimodaler Molekulargewichtsverteilung nur der kurzkettige Anteil berücksichtigt werden. Für 60°C wird unter Anfangsbedingungen k2w/ka = 1,75.10−5 dm3.mol−1. s−1 und der Radikalausbeutefaktor f = 0,58 gefunden. Die kinetischen Konstanten unterscheiden sich nicht von denen der Lösungspolymerisation.
The addition halogenation of polyalkenamers. IV. X‐ray structures of the crystalline chain segments of chlorinated cis‐ and trans‐1,4‐polybutadienes
Authors: Bassi I. W. , Scordamaglia R. 
Published: April 2003

AbstractThe addition chlorination products of trans‐1,4‐polybutadiene and cis‐1,4‐polybutadiene are slightly crystalline. The interpretation of the X‐ray fibre patterns has shown that the crystalline segments obtained from trans‐1,4‐polybutadiene are diisotactic poly(erythro‐1,2‐dichloro butamer) while the crystalline segments obtained from cis‐1,4‐polybutadiene are disyndiotactic poly(threo‐1,2‐dichloro butamer).
Recherche de polymères «Absorbeurs UV». Synthèse et polymérisation de nouveaux monomères du type vinyl‐4 benzophénone méthoxylée
Authors: Pinazzi Chr. P. , Fernandez A. 
Published: April 2003

AbstractLes p‐vinyl benzophénones méthoxylées ont été synthétisées par action du chlorure de p‐vinyl phényl magnésium sur les benzaldéhydes méthoxylés suivie de l'oxydation des p‐vinyl benzhydrols obtenus. Les monoméres ont été polymérisés par procédure radicalaire en solution. Cette réaction conduit, dans le cas de la benzophénone diméthoxylée, à des polyméres de grandes masses. Ces polymères seront partiellement déméthoxylés dans un prochain travail afin de faire apparaître les propriétés d'absorbeurs UV.
Thermodynamic parameters of the helix → coil transition of poly(L‐tyrosine) in mixed organic solvents
Authors: Quadrifoglio Franco , Giancotti Vincenzo , Crescenzi Vittorio 
Published: April 2003

AbstractThe helix → coil transition of poly(L‐tyrosine) in dimethylsulfoxide/trimethylphosphate and in dimethylsulfoxide/dimethylformamide solution, induced by either changing the solvent composition (at 25°C) or by changing the temperature was studied calorimetrically (heat of dilution experiments) and by means of optical activity measurements, respectively. The calorimetric enthalpy of transition, in particular, and the VAN'T HOFF heat of transition of poly(L‐tyrosine) at 25°C resulted, dependent upon the mixed solvent considered. As a consequence, the σ parameter of the theory of ZIMM and BRAGG appeared solvent dependent in the case studied by us.

Authors: Bleha T. , Valko L. 
Published: April 2003

AbstractThermodynamic state equations have been derived making possible to determine the temperature coefficient of unperturbed chain dimensions from thermoelastic measurements of swollen polymer in phase equilibrium with the diluent. Unlike the analysis used previously, the equations derived in the present paper include also the effect of diluent quality on unperturbed chain dimensions.
Effects of aldehyde on stereoregularity of poly(vinyl trifluoroacetate) obtained by radical polymerization
Authors: Matsuzawa Shuji , Yamaura Kazuo , Noguchi Hiroji 
Published: April 2003

AbstractVinyl trifluoroacetate was polymerized by free radicals in various aldehydes at temperatures between −40 and 60°C. The syndiotactic and isotactic diad contents of the polymer were determined through the triads obtained by NMR spectra. The differences of activation enthalpies and entropies of isotactic and syndiotactic arrangement were calculated from the temperature dependence of the ratio of isotactic and syndiotactic diads. In the case of the applied aldehydes, a compensation effect exists between the two quantities, the values of which differ from the values of alkanes, vinyl trifluoroacetate, esters and ketones. The syndiotactic diads of a polymer prepared in aldehydes at 60°C vary from 54 to 56% and are higher than those for the other solvents (50–53%), but the temperature dependence is scarcely low. We consider that the interaction between the fluor atoms in the trifluoroacetyl group of vinyl trifluoroacetate and the π‐bond in the aldehyde affect the stereoregularity.

High resolution NMR studies on oligo‐(oxy‐2,2‐dimethylethylenecarbonyl) compounds
Authors: Ogawa Etsuyo , Kondo Shoichi 
Published: April 2003

AbstractTerminal group effects and solute‐solvent interactions of α‐(3‐hydroxy‐2,2‐dimethylpropionyl)‐ω‐isobutoxyoligo(oxy‐2,2‐dimethylethylenecarbonyl) compounds (Ia—h) and α‐dichloroacetyl‐ω‐isobutoxyoligo(oxy‐2,2‐dimethylethylenecarbonyl) compounds (II a—h) were studied using high resolution NMR technique in four solvents.The signals of these spectra are assigned by comparing the spectra of these oligomers with the spectra of partially deuterated oligomers. The terminal hydroxyl or dichloroacetoxy group affects the chemical shifts of the methylene groups of the oligomers of type I and II. The terminal hydroxyl shows an influence on the chemical shifts up to the methylene units in the fifth monomeric unit, or up to the protons attached to the 18th carbon atom in these oligomers. It is observed that the chemical shifts of the protons depend on the temperature except for the methylene protons close to the center of the chain.
Polyanion — polycation interactions, 1
Authors: Pal M. K. , Ghosh A. K. 
Published: April 2003

AbstractThe interaction between the basic proteins lysozyme or ribonuclease and polyanions like chondroitin sulphate, DNA or inositol hexasulphate and also ferrocyanide was studied conductometrically and turbidometrically. In the conductometric titrations of the polyanions with basic proteins, breaks in the titration curves were obtained at the stoichiometric amounts. Additional breaks were observed at lower and higher protein concentrations with constant amounts of the polyanions. Thus, two equivalent weights, 840 and 1760, of the basic protein lysozyme were obtained. With DNA, however, only one break was obtained at a concentration higher than the stoichiometric amount, indicating that all the phosphate groups of DNA are not involved in the interaction with the proteins. Turbidometric titrations of lysozyme by the polyanions in water, in a buffer or in aqueous ethanol generally gives one break and the equivalent weight of the protein, calculated from this break, corresponds to the higher value determined conductometrically. Ribonuclease gave higher turbidity than lysozyme under identical conditions of polyanions and pH.It is concluded that interaction between polyanion and polycation is stoichiometric only under favourable conditions. Salts initially increase the turbidity produced by a polyanion/polycation interaction followed by a progressive decrease; in this respect bivalent cations are more effective than monovalent cations.

Über die polymerisation von 2,5‐dioxo‐1,3‐oxathiolan und 2,4‐dioxo‐1,3‐dithiolan
Authors: Kricheldorf Hans R. , Bösinger Klaus 
Published: April 2003

AbstractDie Polymerisation von 2,5‐Dioxo‐1,3‐oxathiolan (1a) mit verschiedenen tertiären Aminen wird untersucht. Die Wirksamkeit der Katalysatoren hängt ausschließlich von ihrer Basizität ab. Eine CH‐Deprotonierung beim Monomeren wird als Startreaktion, eine anionisch ringöffnende Polymerisation als Wachstumsreaktion diskutiert. Sowohl bei der Polymerisation von 1a als auch von 2,5‐Dioxo‐1,3‐dithiolan (2a) hat der Wassergehalt des Lösungsmittels oder die Anwesenheit anderer Protonendonatoren einen starken negativen Einfluß auf Ausbeute und rel. mol. Masse des resultierenden Polyesters, während elektrophile Reagenzien wie Alkyl‐ oder Säurehalogenide eine geringere Wirkung zeigen. Unter vergleichbaren Bedingungen polymerisiert 2a wesentlich schneller als 1a und liefert auch Polyester mit wesentlich höheren rel. mol. Massen (bis 112000).

AbstractAs a functional vinyl monomer containing the 10‐isoalloxazinyl (2,4‐dioxo‐3H,10H‐benzo[h]pteridin‐10‐yl) residue, 10‐(2′‐methacryloyloxyethyl)‐3H,10H‐benzo[h]pteridine‐2,4‐dione (2) was prepared by reacting 10‐(2′‐hydroxyethyl)‐3 H,10H‐benzo[h]pteridine‐2,4‐dione (1) with methacryloyl chloride in hexamethyl phosphoric acid triamide solution. Polymerization and copolymerization of the monomer were carried out by 2,2′‐azoisobutyronitrile. Alternatively, vinyl‐type polymers containing the isoalloxazine system (3) were also prepared by a polymer‐analogous reaction. Dehydrogenation reaction of methylmandelate was studied with a copolymer in dimethylformamide solution.
Séparation d'un copolymère greffé de l'homopolymère correspondant par la méthode des gels réversibles, 1. Introduction et principe de la méthode — formation de gels réversibles
Authors: Llauro‐Darricades Marie‐France , Banderet Albert , Riess Gérard 
Published: April 2003

AbstractUne nouvelle technique, basée sur la formation de gels réversibles, est proposée pour la séparation d'un copolymère greffé de l'homopolymère correspondant aux greffons. La mise au point de la méthode a été faite en vue de son application aux résines ABS.On montre ainsi que si le tronc porteur des greffons (polybutadiène) a été muni de groupes COOH, une réticulation réversible peut être obtenue par association dipolaire des groupes COOH salifiés (p. ex. par CH3ONa). A partir d'un tel polymère, en solution dans un mélange de solvant apolaire et d'un solvatant (CH3OH) des associats COONa, on provoque la gélification par élimination du solvatant. Cette réticulation par association entre dipoles COONa permet l'insolubilisation presque totale du polymère carboxylé.Une nouvelle addition de solvatant provoque la dissolution de la phase gel.Le mélange benzène/CH3OH a été choisi pour effectuer les cycles gélification‐dégélification, le méthanol pouvant être éliminé aisément par distillation azéotropique à température ordinaire.Les conditions optimales de formation du gel réversible ont pu être définies.Cette technique de séparation sol‐gel peut être transposée aux copolymères greffés, en vue de leur purification.

It was found that a high m‐value of 24,2 was obtained in the case of the ratio (2/3 trimesic acid)/adipic acid = 0,1 and a decrease of m with an increasing mole ratio of trans‐2,5‐dimethylpiperazine/hexamethylenediamine.
Novel polycations containing nucleic acid bases, 1. Syntheses and interactions in solution with polynucleotides and with related compounds

Published: April 2003

AbstractCationic model compounds of polynucleotide, i.e., poly{1‐[2‐(adenin‐9‐yl)ethyl]‐4‐pyridinioethylene chloride} (1), poly{1‐[2‐(thymin‐1‐yl)ethyl]‐4‐pyridinioethylene chloride} (2), and poly{1‐[2‐(theophillin‐7‐yl)ethyl]‐4‐pyridinioethylene chloride} (3), were synthesized by the MENSCHUTKIN reaction of poly(4‐pyridylethylene) with 9‐(2‐chloroethyl)adenine, 1‐(2‐chloroethyl)thymine and 7‐(2‐chloroethyl)theophylline.The interactions between the model compounds and polynucleotides and between the model compounds themselves were studied by spectroscopy. The apparent hypochromicity was about 20% for the mixture of 1‐Poly A, 15% for that of 1‐DNA and 11% for the 1–3 mixture. The systems 1–2 and 2–3 showed rather small hypochromicities, being 8 and 6%, respectively. The hydrogen bond formation between complimentary bases is not a main factor in the intermolecular interactions in the present cases, but the hydrophobic interactions are suggested to be overwhelming. The UV absorbance of 1–2 or 2–3 mixtures decreased with increasing temperature, confirming the important rǒle of the hydrophobic interactions.
Studies on the polymerization of vinyl compounds in the presence of metal salts, 9. On the initiation mechanism of polymerization of acrylamide by ceric salt
Authors: Narita Hiroshi , Okimoto Tomoyuki , Machida Seishi 
Published: April 2003

AbstractIn order to elucidate the initiation mechanism of the polymerization of acrylamide by ceric salt, the complexation of ceric salt with acrylamide and its methylated derivatives was investigated by IR and NMR spectrometry. The decomposition of the complex was also studied by determining the rate of ceric salt consumption. From the results it was concluded that the oxygen of acrylamide coordinates with the ceric ion to form the complex and that a radical is produced by abstraction of a hydrogen atom from the amide group of the molecule to initiate the polymerization.
Electrostatic effect on electron‐transfer reactions of cobalt(III)‐poly(4‐vinylpyridine) complexes
Authors: Tsuchida Eishun , Karino Yukio , Nishide Hiroyuki , Kurimura Yoshimi 
Published: April 2003

AbstractReductions of cis‐[Co(en)2PVPCl]2+ (1) [PVP = poly(4‐vinylpyridine)] by ferrous aquoions and ferrous chelate ions were studied. The rate of reduction by Fe2+ is small compared to that of the monomeric analogue, cis‐chlorobis(ethylenediamine)pyridine cobalt(2+) (cis‐[Co(en)2PyCl]2+) due to the electrostatic repulsion. On the other hand, the reduction by [Fe‐(edta)]2− is accelerated by a factor of 20. With increasing degree of coordination the acceleration factor increases, and with increasing ionic strength the factor decreases. The acceleration was found to be due to the electrostatic attraction of the reductant by the polymer as a polycation. The electrostatic effect is discussed in comparison with the catalysis of polyelectrolytes in ionic reactions.
Mechanical denaturation of high polymers in solutions, 32. effect of flow pattern on shearing stress‐induced crystallization of poly(vinyl alcohol) from its aqueous solution
Authors: Yamaura Kazuo , Karaki Takao , Matsuzawa Shuji 
Published: April 2003

AbstractThe crystallization of poly(vinyl alcohol) (PVA) from an aqueous solution was carried out under a steady‐state flow. The fibrillar crystals occur just under the surface of the solution after a few seconds of stirring and they grow gradually. The fibrillar crystals are produced even from a 0,05% solution. The process of crystallization of PVA under steady‐state flow was classified in seven types. The rate of precipitation increases with decreasing distance between the surface of a cylindrical stirrer and the wall of a test tube or with the diameter of the stirrer.
Size and orientation of cristallites in lightly cross‐linked polyethylene, crystallized from the melt under uniaxial compression
Authors: Kitamaru Ryozo , Hyon Suong Hyu 
Published: April 2003

AbstractIf lightly cross‐linked polyethylene films are crystallized from the melt under uniaxial compression, a very unique alignment of the molecular chains in the crystalline phase of the samples appears. The orientation of crystallites in which the (200) crystal plane is located parallel to the film surface first appears at a relatively low degree of compression, and subsequently the orientation in which the (110) crystal plane is located parallel to the film surface follows at higher degrees of compression.Despite the fact that the samples were crystallized from the melt rather rapidly, the unitcell density of the crystalline phase was very close to unity and the size of crystallites was very large. The dimensions of crystallites in the direction perpendicular to the film surface were in a range of 170—350 Å but they were as large as more than 1500 Å in the direction parallel to the film surface. Thus it is confirmed in addition by electron microscopic observation that these samples have a new type of lamellar structure in which the molecular alignments are quite different from those for the so‐called lamellar structure for polyethylene crystallized under isotropic conditions.

AbstractFormation, optical properties and structures of bis(o‐hydroxybenzylideneamine)copper(II) chelates of poly(L‐lysine), poly(L‐ornithine), and poly(L‐α,β‐diaminobutyric acid) were investigated.Experimental evidence was obtained for a definite structure of these polycomplexes in alcoholic/aqueous solution. Structural features showed that asymmetric polypeptide matrices bind metal chelates stereospecifically. On the basis of these results stereoselective reactions on bis(o‐hydroxybenzylideneamine)copper(II) polycomplexes are expected.
