【Abstract】 Obtain different crystalline states of polypropylene using the experimantal method and from SEM or results of experiment do some consequence and discussion. Look into the effect on melting flow rate, thermal and physical mechanics properties at different crystalline states of polypropylene. The result shows that the effect of different type of crystalline states on properties of polypropylene is not alike.更多还原
