Volumetry and differential-scanning-calorimetry (DSC) were used to determine decomposition rates; first order kinetics was found in all cases.

    Notes: Summary The chain transfer constants of various aliphatic compounds in the free radical polymerization of styrene and methyl methacrylate have been determined at 60°C. It has been found that some cycloaliphatic compounds show a remarkable chain transfer activity, which can also be of practical interest.

    Zur Struktur von verfÄrbten Polyvinylacetaten (1962)

    Description / Table of Contents: Summary Treating of polyvinyl acetates with p-toluenesulfonic acid and also with some other reagents leads to splitting off of acetic acid and to the formation of conjugate-dunsaturated sequences in the polymer chains. These diene-structures are responsible for the observed colour-changes. By spectroscopic observations and comparison with model compounds it may be concluded that the sequences contain2–12conjugated double bonds.
    Notes: Zusammenfassung Bei der Behandlung von Polyvinylacetaten mit p-ToluolsulfonsÄure und verschiedenen anderen Reagenzien in siedendem Toluol entstehen unter EssigsÄureabspaltung konjugiert-ungesÄttigte Kettenabschnitte in den Polymeren. Die gebildeten Dienstrukturen sind für die dabei beobachteten VerfÄrbungen verantwortlich. Aus spektroskopischen Untersuchungen der verfÄrbten Polymeren kann an Hand von Modellverbindungen geschlossen werden, da\ die Zahl der miteinander in Konjugation stehenden Doppelbindungen zwischen zwei und zwölf liegt.

    Oligomers of α-methylstyrene by initiation with tetraphenylethanes (1986)
    Springer
    Polymer bulletin 16 (1986), S. 19-26 
    Details
    ISSN: 1436-2449
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Summary With substituted tetraphenylethanes as polymerization initiators, telechelic oligomers of ∝ -methylstyrene were obtained above ceiling temperature, contrary so far to other free radical reactions using e.g. chain transfer agents. In the here investigated system tetraphenylethanes act as initiators and terminating agents. The C-C bond between the last monomer unit of the oligomer and the terminating end group from the initiator can be thermally cleaved at about 50°C which produces free radcials. Thus, these ∝ -methylstyrene oligomers can be applied as initiators of freeradical polymerization, e.g. for styrene or methyl methacrylate.

    Keywords: Azoesters, synthesis, decomposition ; Azoisobutyronitrile
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Azoesters of the typePhR 1R2CN=NCR 2R1Ph(R 1=alkyl,R 2=rest of carboxylic acids) were synthesized; their 10h-half-life-temperatures and energies of activation of the decomposition were determined. The decomposition of the azo compounds follows a law of first order. The variation of the substituentsR 1 andR 2 gives information about the effect on the decomposition of the azo compounds. The azoesters of acetic acid are outstanding by low temperatures of decomposition and are situated in the range of azoisobutyronitrile.

    Notes: Abstract For further investigation of the relations between the structure and the decomposition of the azoesters of the typePhR 1 R 2CN=CNR 2 R 1 Ph two supplement series (R 1=CH3, C2H5;R 2=substituted acetic acids) were synthesized. Especially information were obtained concerning the reasons for the low temperatures of decomposition of the azoesters of acetic acid. The azoesters of the substituted acetic acids follow a law of first order for the decomposition.

    Über die chemische Reaktivität vernetzter Perlpolymerisate aus Styrol, p-Jodstyrol und Divinylbenzol (1966)
    Springer
    Colloid & polymer science 211 (1966), S. 8-13

    Description / Table of Contents: Summary Crosslinked bead copolymers from styrene, p-iodostyrene and divinyl benzene can be completely deiodinated under suitable conditions by reaction with n-butyl lithium to yield crosslinked polystyrene. Prerequisite is a sufficient swelling of the beads in the reaction medium which depends on the degree of crosslinking of the polymer and on the solvent used for n-butyl-lithium. The deiodinated polymers swell in benzene to a greater extend than does polystyrene with the same content of divinyl benzene monomer units; this is atributed to the formation of pores in the network by replacement of the large iodine atoms by smaller hydrogen atoms.
    Notes: Zusammenfassung Vernetzte Perlpolymerisate aus Styrol, p-Jodstyrol und Divinylbenzol lassen sich unter bestimmten Bedingungen quantitativ entjodieren durch Umsetzung mit n-Butyllithium. Voraussetzung ist dazu eine hinreichende Quellbarkeit der Perlen in dem verwendeten Reaktionsmedium; dies hängt vom Vernetzungsgrad des Polymeren sowie vom Lösungsmittel für das n-Butyllithium ab. Die entjodierten Polymeren quellen in Benzol stärker als gleich stark mit Divinylbenzol vernetzte Polystyrole, was auf die Bildung von Hohlräumen in den Polymeren durch Ersatz der großen Jodatome durch Wasserstoffatome zurückgeführt wird.
