[0331] C Comparative Experiment

[0332] 3. Method of Measurement

[0333] In each case, polymeric films are prepared with the dispersions specified in Table 1. For this purpose, a film is applied to release paper with the aid of a slotted doctor knife. The doctor knife is placed on the paper. In front of the slotted doctor blade, the liquid solution is applied to the paper with a pipette. A thin film, ca. 0.5 mm thick, is applied between the gap and the paper by peeling it off. This film is dried for 24 hours until it is no longer damp and is completely cured. Sample of ca 4 mm length are cut to generate hysteresis curves. A ZwickiZ2.5 tensiometer from Zwick Roell was used for the measurements.

[0334] The hysteresis measurements were carried out as follows:

[0335] Elongation 100% (see Tables 2, 3 and 4):

[0336] A load is applied to the samples to lengthen them to 100% elongation at a rate of 50 mm/min. Then the load is removed until the specimen has assumed the length of the original length—remaining elongated. This procedure is repeated ten times with each sample.

[0337] Elongation 500% (see Tables 5, 6 and 7):

[0338] A load is applied to the specimens to elongate them stepwise to a lengthening of 50 to 500% at a rate of 50 mm/min. After each lengthening, the load is removed until the specimen has assumed the length of the original length—remaining elongated.
