Infrared study of the reaction of polyisoprene and polybutadiene with sulfur by use of deuterated polymers
Autor: M. A. Golub, J. J. Shipman
Publikováno v: Journal of Polymer Science. 58:1063-1082
An infrared study of the sulfur vulcanization process was carried out with very high cis polymers of isoprene-d8, isoprene-3-d1 and butadiene-2,3-d2 as well as the corresponding perprotio polymers. The use of deuterated polymers permitted more defini

Reaction of Deuterio Polyisoprene and Deuterio Polybutadiene with Sulfur
Autor: J. J. Shipman, M. A. Golub
Publikováno v: Rubber Chemistry and Technology. 36:219-235
Infrared absorption spectroscopy has been employed in the past in efforts to determine the nature of the chemical changes which occur in natural rubber during vulcanization. The most prominent change in the infrared spectrum of rubber accompanying vu

The important observation made by Katz in 1925, using x-ray diffraction technique, showed that the mere stretching of crude or soft vulcanized Hevea rubber caused at least a portion of the polymer to undergo crystallization. This and the subsequent e

Characteristic infrared frequencies of rotational isomers of alkyl chlorides
Autor: J. J. Shipman, V. L. Folt, Samuel Krimm
Publikováno v: Spectrochimica Acta. 18:1603-1613
A study of the infrared spectra of primary, secondary and tertiary alkyl chlorides reveals that the frequency of the so-called C-Cl stretching mode is a function of the detailed structure in the vicinity of the C-Cl bond. In primary chlorides the fre
