Stress relaxation measurements in simple exten6ion of three commercial samples of polyisobutylene (PIB) of different viscosity molecular weights (1.1, 1.7 and 2.3 x 106) have been made at stretch ratios (,~) up to about 2. Data obtained at 3 ยฐ and 50 ยฐ have been reduced at 25 ยฐ. As already found pre
