title: [State of order, properties and dynamics of structure in shear-crystallized ointments (author's transl)].
abstract: Using polyethylene-ointments the influence of different stirring rates upon the course of melt-congealing and upon the forming of rheological properties was investigated. Shearing disturbs the process of ordering in the solid phase and causes a higher strength of the ointment. During storage the viscosity increases in the nonsheared ointments and it decreases in the sheared ones. Both systems tend to form a dynamic equilibrium of order characterized by relative intensive lattive defects in the solid phase of the gel matrix.
