Abstract
The complex strain-optical coefficient and the complex Young’s modulus of an amorphous polyolefin, poly[1-ethyl-5-methyl-octahydro-4,7-methano-1H-indene-12,3-diyl], PEMOMID, were measured around the glass-to-rubber transition zone. The data was analyzed with a modified stress-optical rule, and two components of complex modulus, EG* and ER*, and two associated stress-optical coefficients, CG and CR, were determined. The result was compared with one for a Bisphenol A polycarbonate, PC. CR, stress-optical coefficient in the rubbery plateau zone, for the polyolefin was 1.7×10−9 Pa−1 and about three times smaller than that for PC. CG for PEMOMID is negative and this was in contrast to a usual positive value for polymers containing phenyl rings in their repeating units.
