    Notes: A detailed protocol is presented for precisely inserting microscopic objects into the periplasmic region of plant callus cells using laser microsurgery. Ginkgo biloba and Agrobacterium rhizogenes were used as the model system for developing the optical tweezers and scalpel techniques using a single laser. We achieved better than 95% survival after plasmolyzing G. biloba cells, ablating a 2-4-μm hole through the cell wall using a pulsed UV laser beam, trapping and translating bacteria into the periplasmic region using a pulsed infrared laser beam, and then deplasmolyzing the cells. Insertion of bacteria is also described. A thermal model for temperature changes of trapped bacteria is included. Comparisons with other methods, such as a reverse-pressure gradient technique, are discussed and additional experiments on plants using laser microsurgery are suggested. © 1998 John Wiley & Sons, Inc.

    Description / Table of Contents: Die Chlorwasserstoffabspaltung am Polyvinylchlorid wurde in phenolischen Lösungsmitteln unter Stickstoffatmosphäre im Bereich von 137° bis 206°C untersucht. Phenol, o-Cresol, Methyl-, Äthyl-, Amyl- und Phenylsalizylat wurden als Lösungsmittel verwendet. In Phenol war die Reaktion schnell und in Amylsalizylat langsam. Mit zunehmender Größe des Alkylrestes im Salizylat nahm die Geschwindigkeit der Abspaltung des Chlorwasserstoffs ab. In Amylsalizylat war die Aktivierunsenergie niedriger (26 Kcal/mol) als in o-Cresol (29 Kcal/mol) bei den anderen Lösungsmitteln lagen die Werte dazwischen. Die Ergebnisse lassen sich durch die unterschiedliche Aktivität des phenolischen Wasserstoffs und die sterische Hinderung der verschiedenen Lsöungsmittel erklären.
    Notes: The thermal degradation of polyvinyl chloride in phenolic solvents has been investigated in an atmosphere of nitrogen in the temperature range 137-206°C. The solvents used were phenol, o-cresol, methyl, ethyl, amyl, and phenyl salicylates. The reaction was fast in phenol and slow in amyl salicylate. The rate of dehydrochlorination decreased with increasing size of the alkyl side chain in salicylates. The activation energy was low in amyl salicylate (26 kcal/mole) and high in o-cresol (29 kcal/mole), and for other solvents it was in between these two values. The results have been explained as being due to the variation in the reactivity of phenolic hydrogen and to steric factors of the various substituents.

    Description / Table of Contents: Die Chlorwasserstoffabspaltung aus Polyvinylchlorid wurde in 2-Allylphenol, 2-Allyl-6-methylphenol und 2-Methoxy-4-allylphenol (Eugenol) unter Stickstoff im Bereich von 188-218°C untersucht. In Eugenol war die Reaktion langsam. In Eugenol war die Aktivierungsenergie niedriger (40 kcal/mole) als in 2-Allylphenol (47 kcal/mole); bei 2-Allyl-6-methylphenol lagen die Werte dazwischen. Die Reaktion ist autokatalytisch. Die Chlorwasserstoffabspaltung wird in Äthylbenzoat und Methylsalizylat durch kleine Zusätze von Eugenol verlangsamt. Die Ergebnisse lassen sich durch einen Radikal-Mechanismus für die Chlorwasserstoffabspaltung erklären.
    Notes: The thermal degradation of polyvinylchloride in 2-allyl phenol, 2-allyl-6-methylphenol and 2-methoxy-4-allyl phenol (eugenol) has been investigated in an atmosphere of nitrogen in the temperature range 188-218°C. The reaction is very slow in eugenol. The activation energy was lower in eugenol (40 kcal/mole) than in 2-allyl phenol (47kcal/mole). The reaction is autocatalytic. The rate of dehydrochlorination in ethylbenzoate or methylsalicylate is suppressed by addition of small quantities of eugenol. The results have been explained on the bases of a free radical mechanism for the dehydrochlorination reaction.

    Description / Table of Contents: Die Spektren im sichtbaren Bereich von Polyvinylchloride(PVC), das im Vakuum in Methylsalicylat, Amylsalicylat und 2-Methoxy-4-allyphenol (eugenol) abgebaut wurde, werden beschrieben. Auf der Basis des Gehaltes der in PVC gebildeten Doppelbindungen ergibt sich hinsichtlich der Abbaugeschwindigkeit folgende Reihenfolge der Lösungsmittel: Methylsalicylat 〉 Amylsalicylat 〉 Eugenol. Für die Beteiligung der Lösungsmittel wird ein radikalischer Mechanismus vorgeschlagen. Die Aktivierungsenergie für die Bildung der Doppelbindungen in Methylsalicylat im Temperaturbereich von 176 bis 208 °C wurde zu 21±0,5 kcal/Mol bestiment.
    Notes: The visible range spectra of polyvinylchloride (PVC) degraded in vacuum in methylsalicylate, amylsalicylate and 2-methoxy-4-allylphenol (eugenol) are reported. On the basis of the percentages of double bonds formed in PVC the following reactivity order was assigned to the solvents methylsalicylate 〉 amylsalicylate 〉 eugenol. A free radical mechanism is proposed for the solvent participation. The activation energy for the overall double bond formation in methylsalicylate in the temperature range 176-208°C was found to be 21±0.5 kcal/mole.

    Description / Table of Contents: Methylhydro-dimethylsiloxancopolymere wurden aus den Hydrolysaten von Dichlordimethylsilan mit 10, 20, 30, 50 und 70 Vol.-% Dichlormethylsilan hergestellt. Die Copolymeren wurden IR-, 1H-NMR-spectroskopisch und chemisch charakterisiert und als Härter für ein funktionalisiertes RTV-Siliconmaterial eingesetzt. Die Vulkanisateigenschaften wurden geprüft; die Copolymeren mit hohem Hydridgehalt verbesserten die mechanischen Eigenschaften und die thermische Stabilität der Vulkanisate.
    Notes: Synthesis of hydride terminated methylhydro-dimethylsiloxane copolymers from the hydrolyzates of 10, 20, 30, 50 and 70% vol.-% dichloromethylsilane with dichlorodimethylsilane have been carried out. The copolymers were characterized by IR-and 1H-NMR-spectroscopy and standard chemical analysis. They were used as curatives for a standard vinyl functional room temperature vulcanizing (RTV) silicone material based on addition cure, and the vulcanizate properties have been evaluated. The copolymers with high hydride content gave better mechanical properties and thermal stability to the vulcanizates.
