The silicone rubber based on PDM-MVS/PMMA blend had microphase-separated structure consisting of PMMA domains uniformly dispersed within a continuous PDM-MVS matrix.

结果表明，随着PDM-MVS中乙烯基质量分数的增加，共混物的黏度逐渐增大；由PDM-MVS/PMMA共混物制备硅橡胶的物理机械性能明显优于α，ω-羟基聚二甲基硅氧烷／PMMA共混物制备的硅橡胶；制得的硅橡胶具有微观相分离结构，PMMA分散相均匀地分布于PDM-MVS连续相中，两相的相容性良好。
