| Abstract: | Styrene acrylic emulsion modified by different contents of vinyl silicone was prepared,and the effects of the silicone content on the latex particle size,glass transition temperature and thermal stability of latex film was studied.The results show that vinyl silicone can improve glass transition temperature and thermal stability of latex film.When the silicone content is 5%,the glass transition temperature was improved from 45℃ to 63℃ and thermal decomposition temperature was improved from 327℃ to 384℃. |
