44. Influence of testing conditions on the performance and durability of polymer stabilisers in thermal oxidation

Author

Subjects

Abstract

Information on the efficiency of stabilisers in protecting polymers against thermal oxidation under service conditions is essential for selection and development of appropriate stabilizing systems. Accelerated tests are necessary to get data in an acceptable time and need carefully selected failure criteria. Appropriate testing severity, avoiding misuse of accelerated methods and understanding of the limitations of the methods are essential if reliable data are to be obtained. The potential and limitations of oven ageing tests, oxygen uptake measurements, differential scanning calorimetry (DSC) and chemiluminescence (CL) in stabiliser testing are reviewed.

45. Unusual mass spectrometric fragmentation of N,N′-diethyl- N, N′-diphenylurea.

Author

Hanuš, V., Horák, Z., and Tolman, V.

Abstract

The electron impact mass spectrum of N, N′-diethyl- N, N′-diphenylurea contains the ion m/z 164 which is of low abundance at normal energy of ionizing electrons but prominent at 15-20eV. The mechanism of its formation has been revealed by means of labelled compounds. It is rationalized in terms of an unusual formation of styrene lost as a neutral molecule. [ABSTRACT FROM AUTHOR]
