Firstly,the process of manufacturing the self-made aqueous dispersion of PP and the conditions that have to be controlled are introduced briefly.After that,the self-made aqueous dispersion of PP is used to treat the GF and the effects of them on the crystallization behavior on the interface of GF and PP are observed by using several ways.The results are compared with the GF with other kinds of treatments.In the end,the effects of the aqueous dispersion of PP on the crystallization behavior on the interface of GF and PP are obtained.
