Introduction Recent years have witnessed a great interest in polymeric materials of special properties such as resistance to considerably lowered or elevated temperature, flame-retardation and appropriate mechanical strength

capillary and under pressure values of specific resistance are, respectively: 1.6–3 Ω cm and 1.6–3.3 Ω cm. Values of R 2 were not measurable. Values of inductance were around 2.20 ± 0.03 μH for both samples. The element R 1 - L ( Fig. 8 ) can be

microflow systems in organic synthesis. For the pioneers in the field of microreaction technology, the rising interest, as well as the resistance in application of microreactors in biotechnology, was like a “déjà vu” after almost two decades [ 10 ]. As
