Original Abstract
In this paper are introduced basic methods for measuring the properties of the gel structure during polymerization, particularly relaxation times T1, T2 spin density and diffusion coefficients. We can obtain these parameters using the MR pulse sequences. To measure of relaxation time T1 are used SR techniques (Saturation Recovery) and IR techniques (Inversion Recovery) usually. To measure of relaxation time T2 can be used SE (Spin Echo) technique. To measure diffusion coefficinets are used PFG-SE and PFG-SSE methods (Pulsed Field Gradient Spin Echo a Pulsed Field Gradient Stimulated Echo) and of course their modification. Experiment itself is described sample preparation of gel electrolytes and to measure their relaxation times.
