An independent measurement of the amorphous content of polymers

Roy G. Miller、H.A. Willis1956-03-01Journal of Polymer Science

Abstract Attempts have been made, particularly by American workers, to exploit differences in crystalline and amorphous polymer spectra to determine crystalline/amorphous ratios. In most published work authors have been forced to rely on calibration by other methods, especially density. They have justified the use of…

Die selbstvernetzung von fadenmolekülen

Von Werner Kuhn、H. Majer1956-03-01Die Makromolekulare Chemie

Abstract Eine qualitative Überlegung zeigt, daß sich bei genügend klein gewählter Konzentration einer Polymerlösung die bei konzentrierteren Lösungen nach Zusatz eines Vernetzungsreagenses zu beobachtende Gelbildung unterdrücken läßt. In diesem Falle fällt eine durch das Vernetzungsreagens bewirkte Verknüpfung von in…

Elastic Moduli of Glasses at Elevated Temperatures by a Dynamic Method

S. Spinner1956-03-01Journal of the American Ceramic Society

The elastic constants of thirteen glasses were measured by a dynamic method at elevated temperatures. Both Young's modulus and the shear modulus were determined and from these Pois‐son's ratio was calculated as a function of temperature. Fused silica, Vycor‐brand glass, and Pyrex‐brand glass had positive temperature c…

El autor presenta el Sistema Rotomixair, empleado para la distribución del aire en los secaderos de cámaras. Consiste en un conjunto de ventiladores de unas características especiales, móviles, que se pueden desplazar dentro de la cámara. El secado es rápido.

Investigation of material transport in wet-process rotatory kilns by radio isotopes

J. Rutle1956-03-01Materiales de Construccion

El empleo de isótopos permite estudiar perfectamente el desplazamiento de los materiales a lo largo del horno. en otros aspectos referentes a la influencia de diversos factores sobre el funcionamiento del horno y sobre el proceso de cocción, se llega a la misma conclusión que mediante los métodos clásicos de investiga…

Chain scissions in a polymer network

M. M. Horikx1956-03-01Journal of Polymer Science

Abstract Relations between the soluble fraction and the number of effective chains between crosslinks in a three‐dimensional network undergoing a scission reaction have been derived. Three limiting cases have been considered: (a) random scission in the chains, (b) scission in the chains directed by the crosslinks, and…
