Linear 1,2-polybutadiene, glass transition temperature (T,) -18OC, is crosslinked a t -10' to -2OOC by y irradiation while strained in simple extension, with extension ratios (&) from 1.2 to 2.7. After release, the sample retracts to a state of ease (A,) a t room temperature. From equilibrium stress
