FIG. 1.

Stress-strain curves.

FIG. 2.

Flat camera WAXD patterns of (a) NR-0, (b) NR-20H, and (c) NR-40CA, at strain ratio . Stretching direction is vertical.

Image of FIG. 3.
FIG. 3.

Variation of the integrated intensity of the equatorial reflections, , during the stretching and retracting processes for (a) NR-0, (b) NR-20H, (c) NR-40H, (d) NR-40CA, and (e) NR-60CA. The thick and thin lines indicate the stretching and the retracting processes, respectively. The larger symbols correspond to the stretching process. The data during the stretching process near the onset of crystallization are shown in part (f), from which the values were estimated.

FIG. 4.

Variation of lateral crystallite size, , during the (a) stretching and (b) retracting processes.

FIG. 5.

Variation of azimuthal half-width of 200 reflection, , during the (a) stretching and (b) retracting processes.

Image of FIG. 6.
FIG. 6.

Lattice constants and volume of the unit cell as a function of nominal stress. Both the stretching and retracting processes are included.

FIG. 7.

Relationship between incipient crystallization temperature, , and . The data in Ref. 7 were used for the plot. The number of repeating unit per chain, , for samples 2DC, NN-7, and NN-6 are 198, 140, and 154, respectively. 2DC was cured with dycumil peroxide, and NN-7 and NN-6 were cross-linked by irradiating with radiation.

FIG. 8.

Mechanical model to explain the deformation of crystallites for the filled sample. The filled squares and shaded circles represent NR crystallites and filler particles, respectively.
