## Abstract The dynamic elastic modulus of cellophanes has been measured by use of the resonant frequency of a 2 Γ 60βmm. strip of film in longitudinal vibration. The niodulus was computed from the resonant frequency length of specinieii, and the crossβsectional area determined from its resonant fr

β¦ Synopsis
High precision stress-strain curves were determined from representative Type A Mylar sheets in several commercially available thicknesses. A representative value for Young's modulus was found to be 0.76 X lo6 psi. Measured values were from 0.60 to nearly 0.78 X 106 psi with the maximum value occurring at 0.005-in. thickness.

## Abstract New methods for rapidly obtaining elastic modulus and density measurements during isothermal polymer aging are given. The elastic measurements are performed using a Rockwell hardness tester. In this case, the elastic recovery is measured. Rapid density measurements are performed using a
