ResumoPhase transitions of the PE – xylol, PE – hexane, PE – chloroform, PE – dichlorobenzene, PEG – 1,4-dioxane and PEG – toluene systems, and also the structure of the polymers separated from these systems have been studied using the
cloud-point method, polarizing microscopy and the X-ray diffraction under magnetic field and in its absence.
Phase diagrams of these systems are constructed. It is shown that the magnetic field leads to the increase in polymer crystallization temperatures from solutions and melts.
It is revealed that the sizes of spherulites formed in PEG solutions under magnetic field are significantly smaller, than that in the magnetic field absence.
The crystallinity degree of the PE and PEG samples separated from solutions and melts was determined. It was shown that the magnetic field increases the crystallinity degree of PEG, but doesn't influence on the PE crystallinity degree.
