Abstract:
A chemiluminescence apparatus and method for determining polymer stability by measuring the intensity of the light emitted during thermal oxidation. The apparatus described in the invention measures the light intensity vs. time from polymers in an oxidative atmosphere. On the basis of this information, important parameters such as induction time and oxidation rate can be obtained. The apparatus has the advantage of simultaneous multi-sample analysis and the mathematical approach enables data computerization.
Process For Continuous Production Of Thermosetting Resinous Fibers
The preparation of cured thermosetting resinous fibers for extruding a dried novoloc resin in admixture with a crosslinking agent to a gear pump having a spinnerette connected thereto for issuance of the molten resin from the spinnerette into an atomsphere of an acid gas for cure of the resinous fibers issuing from the spinnerette.
