Macroscopic visco − elastic properttes of a polymer alloy with an island −sea structure are calculated under 七 he shear appl 重 ed stτ ess by using the equivalent inclusion methQd combined with the Mori − Tanaka theorem . The effects of the shape and the shear modulus of the spherical island particle on the macroscopic shear mQdu 五 us and Ioss factor of the polymer alloy are crali 丘ed in the lbrm of the two − dimensionai contour map , Consequently , 重 t is found that an optimum range on the
