摘要：

A new kind of rubber powder with "salami" structure (RPS) was prepared by spray drying the mixture of styrene-butadiene rubber latex and nano-CaCO3 slurry. It was found that RPS is an effective toughener with synergistic toughening effect on poly(propylene) (PP). The Izod impact strength of PP/RPS blend is not only higher than that of PP/rubber powder or PP/nano-CaCO3 blends, but also higher than that of a PP/rubber powder/CaCO3 blend. TEM images show that the microstructure of the PP/RPS blend is an "island-sea" structure with "salami" structure in RPS, in which nano-CaCO3 particles are embedded in styrene-butadiene rubber particles. The relationship between properties and microstructure has been studied by using TEM, SEM, DSC, etc.
