    Hydroxyl-modified epoxy resins: Some technical and analytical aspectsDedicated to Professor Dr. H. Batzer in honour of his 60th birthday (1980)
    New York : Wiley-Blackwell
    Die Makromolekulare Chemie 181 (1980), S. 1-17

    Topics: Chemistry and Pharmacology , Physics
    Notes: The modification of epoxy resins by reactions involving their hydroxyl groups is described. For example, reactions with enol ethers, acrylonitrile, ethyl acetoacetate and certain other carboxylic esters, or triethyl orthoformate, gave products which had reduced reactivities towards various hardeners, and which therefore gave lower peak temperatures on cure and/or longer usable lives. Suitable modification of epoxy resins with various other reagents(certain acid anhydrides, epichlorohydrin, or N-hydroxymethylacrylamide) introduces additional useful functional groups. The uses of a diisocyanate and of α-naphthyl isocyanate to modify epoxy resins or their mixtures prior to GPC analysis are also mentioned.

Es wurde gefunden, daß die Verbindungen [π-C5H5Fe(CO)2R] (R = CH3, CH2C6H5) und [π-C5H5Mo(CO)3CH3] wirksame lichtempfindliche Beschleuniger für die Anhydridhärtung von Expoxidharzen sind. Der Aktivierungsmechanismus wird diskutiert.
    Notes: Compounds of the types [π-C5H5M(CO)nX] (M = Fe, n = 2; M = Mo, n = 3; X = CH3, CH2C6H5, CH2Si(CH3)3, CH2OCH3, Sn(C6H5)3, SnCl3, HgCl, I), [Mn(CO)5CH3], and [(π-CH3C5H4)Mn(CO)3] have been examined as catalysts for the cure of epoxy resins under various conditions. It was found that the compounds [π-C5H5Fe(CO)2R] (R = CH3, CH2C6H5) and [π-C5H5Mo(CO)3CH3] are active photosensitizing agents for the anhydride cure of certain epoxy resins.

    Description / Table of Contents: Es wurden die Verschiebungen untersucht, die durch Tris-(dipivaloylmethano)-europium und Tris-(dipivaloylmethano)-praseodym im NMR- Spektrum versehiedener Derivate substituierter Phenole hervorgerufen werden. Der Zweck dieser Arbeiten war, die Möglichkeiten zu erfassen, die diese Verschiebereagenzien als Hilfsmittel in der NMR-Analyse von Phenolharzen bieten, und Information über Verschiebungen bei Molekülen zu gewinnen, die mehr als eine Koordinationsposition besitzen.
    Notes: An investigation into the shifts induced in the NMR spectra of some derivatives of substituted phenols by tris(dipivalomethanato)europium and tris(dipivalomethanato)praseodymium is reported. The phenol derivatives were studied to ascertain the possible utility of the shift reagents as an aid in the analysis of phenolformaldehyde resins by NMR spectroscopy, and to gain information on induced shifts with molecules having more than one possible co-ordination site.

    Description / Table of Contents: 13C-und 1H-NMR-Untersuchungen haben überzeugend gezeigt, daß die Hauptkomponente des Epoxidharzes aus Phenolphthalein und Epichlorhydrin ein aromatischer Diglycidyläther mit einem Lactonring ist und nicht eine chinoide Verbindung mit Glycidylätherund Glycidylesterstruktur.
    Notes: 13C- and 1H-NMR studies have shown conclusively that the main component of the epoxy resin derived from phenolphthalein and epichlorohydrin is an aromatic diglycidyl ether containing a lactone ring, rather than a glycidyl ether-glycidyl ester compound containing a quinoid ring.

    Effects of molecular asymmetry on 13C chemical shifts in some O- and N-glycidyl compounds (1976)

    Notes: In the 13C—{1H} n.m.r. spectra of certain organic compounds containing two or three glycidyl (2,3-epoxyprop-1-yl) groups, chemical shift nonequivalence has been observed, between diastereoisomers, for chemically similar carbon atoms in the glycidyl groups. Nonequivalence was only apparent when the glycidyl groups were linked through a single atom. In three derivatives of diglycidylaminobenzene, 13C chemical shift nonequivalence was also observed for aromatic carbon atoms ortho to the nitrogen substituent.

    Description / Table of Contents: Der Einfluß der sterischen Anordnung der Epoxydgruppe auf den Härtungsverlauf und auf andere Eigenschaften von Epoxydharzen, die 3-Oxatricyclo[3,2,1,02,4]oct-(6)-yl- oder 4-Oxatetracyclo [6,2,1,02,7,03,5]undec-(9 oder 10)-yl-reste enthalten, wurde untersucht. Die Gasbildung, die während der Härtung gewisser Verbindungen der erstgenannten Klasse mit Anhydriden beobachtet wurde, ist durch eine intramolekulare Reaktion der Epoxydgruppe mit der Brückengruppe zwischen den cyclischen Resten erklärbar. Die Epoxydierung der Tricyclo[5,2,1,02,6]undec-(3)-en-(8 oder 9)-yl-Derivate ist durch eine starke Stereoselektivität gekennzeichnet, und die beiden möglichen sterischen Isomertypen wurden einerseits durch Epoxydierung mit Peressigsäure und andererseits durch Bildung der Chlorohydrin-Acetate und ihre Verseifung und Dehydrochlorierung erhalten. Die relative Reaktivität der beiden stereo-isomeren Reihen wurde untersucht. Das Chlorhydrinverfahren läßt sich wegen der dabei auftretenden Umlagerungsreaktionen nicht für die Epoxydierung von Bicyclo[2,2,1]hept-(5)-en-(2)-yl-derivaten anwenden.Bei Epoxydharzen, die auf der Basis des Cyclohexanrings aufgebaut sind, wurden keine analogen stereochemischen Erscheinungen beobachtet.
    Notes: The effects of the steric environment of the epoxy group on the curing and other properties of epoxy resins containing 3-oxatricyclo [3,2,1,02,4]oct-6-yl and 4-oxatetracyclo[6,2,1,02,7,03,5]undec-9(or 10)-yl residues were examined. During the anhydride cure of certain members of the former class, evolution gas was observed. This is attributed to intramolecular reaction between the epoxide group and the linkage between the two ring systems. Stereoselectivity in epoxidation of tricyclo[5,2,1,02,6]undec-3-en-8(or 9)-yl derivatives is high, and the two possible series of stereoisomers were obtained, by epoxidation with peracetic acid and by formation and saponification-dehydrochlorination of chlorohydrin-acetates, respectively. The relative reactivities of the two stereoisomeric series were examined. The route via the chlorohydrin is not applicable to epoxidation of dehydronorbornyl derivatives, owing to the occurrence of rearrangements.No analogous stereochemical effects were observed with cyclohexane-based epoxy resins.
