Abstract: Abstract The effects of added polyisoprene homopolymer (PI) and polyisoprene‐blockstyrene diblock copolymer (SI) on the viscoelastic properties of a polystyrene‐block‐polyisoprene‐block‐polystyrene triblock copolymer (SIS) having a spherical domain morphology have been examined. The former two species are used to model the effects of imperfections in structures that result from triblock copolymers missing, respectively, two or one polystyrene end blocks. The results indicate that the loss modulus and tangent …
