| Abstract: | Polysilicone was midified with ricinolein polyurethane, and the effect of preparation method and PU concentration in the system on the heat stability and impact behavior of modified systems were investigated. It is shown that the heat stability and impact strength of polyurethane polysilicone systems clearly depend on the content of polyurethane. The preparation methods of modification systems have obviously influence on its impact strength, and small on its heat stability. |
