## Abstract A new kind of rosinβtype nucleating agent for polypropylene (PP), the cocrystal of dehydroabietic acid, potassium dehydroabietate, and sodium dehydroabietate, was prepared, and the effects of the nucleating agents on the mechanical and crystallization properties of PP were also studied.
## Abstract Nucleation characteristics of isotactic polypropylene (iPP) nucleated by the Ξ±/Ξ² compounded nucleating agents (NAs) were investigated by wideβangle Xβray scattering, differential scanning calorimetry and mechanical testing. The results showed that the nucleation effect of the Ξ±/Ξ² compou
