Stirring-induced solution crystallization of ultra high molecular weight polyamide 6

Autor: H. L. Doppert, J. G. Van Dijk

Publikováno v: Journal of Applied Polymer Science. 36:1177-1189

Unstable solutions of ultrahigh molecular weight polyamide 6 have been prepared by adding a nonsolvent to the polymer solution. Crystallization of the polyamide from such a solution proceeds very slowly. It has been found, however, that vigorous stir

Publikováno v: Journal of Polymer Science Part A-1: Polymer Chemistry. 4:2353-2366

This article deals with the kinetics of the retrogradation of amylose in aqueous solutions of pH 4.0, 9.2, and 11.9. The course of the retrogradation is followed by means of light-scattering measurements. From our interpretation of the light-scatteri
