Abstract: The rheological properties of high and low density polyethylene(HDPE and LDPE)melts were investigated by using capillary rheometer,and preliminary verification for the half natural converging angle equation of non-Newtonian fluids which was derived in a prerious work was made.The results showed that the natural convergent angles of the sample melts calculated by using the equation were in correspondence with the values reported in the literature under the relevant conditions.
