| Abstract: | Conclusions Contemporary rapid optical methods have been developed for investigating structural transformations in the precipitation of polymers from solutions, structure study and monitoring during thermal and deformational actions on polymer solutions, films, and fibres.Application of these methods makes it possible to determine basic structural parameters — anisotropy, orientation, size and morphology of supermolecular structures; these characterize operational properties of fibres and films.The experimental assemblies devised on the basis of optical methods with photographic or photoelectric recording of the transmitted and scattered light have improved metrological characteristics; they are universal, and are used to monitor fast-occurring processes of structure-formation in spinning fibres and films without interference into the investigated system.Translated from Khimicheskie Volokna, No. 4, pp. 6–10, July–August, 1986. |
