5. Imagine you are making a plastic hoop by injection molding a molten polymer into a mold. The molten polymer travels in two directions from the injection point, and meets on the opposite side of the hoop. How long do you need to wait after the two streams first meet to develop full mechanical strength at the junction? Assume that for this to occur, polymers at the interface must diffuse a distance r2RgL. Assume also that the polymer is polystyrene with NNe, a viscosity =104Pas, and a plateau modulus Ge=2105Pa
