Crud Chemicals is enviously noticing the market for Tygon flexible tubing. They have developed a linear, amorphous polymer with Tg=-10 degrees C.which they think may be a good competitor in this market. Their polymer has excellent clarity and chemical resistance, but they are not too sure about its mechanical suitability. To check it out mechanically, they extrude some tubing and subject it to rupture tests at 20 deg C.These tests consist of taking a fixed length of tubing, pressurizing it to 50 psi, and determining the average burst time for a large number of samples. The average life of their specimens turns out to be 40 h at 20 deg C. To what common laboratory test of viscoelasticity does this test most closely correspond? Estimate the average life of the same tubing in the same rupture test at 30 deg C and 37 deg C
