Because in this article the few epoxy resin may cause the polyurethane microscopic shape obvious change, we and tanδ~T diagram analyze differently loss modulus diagram according to the epoxy content four charts, this is for elaborates this change clearly.

-This can be caused by a small amount of epoxy resin in micro-morphology of polyurethane clear change, our loss modulus diagram and Tan δ ~T diagram in accordance with the content of different epoxy split a four-picture, this is to clearly set out the changes.
