用超声波测速法研究了固体相容型聚甲基丙烯酸甲酯-聚醋酸乙烯共混物和固体不相容型聚甲基丙烯酸甲酯-聚苯乙烯共混物的性能。结果表明，在共混物中，超声声速随其组成呈线性变化；在不相容共混物中，它偏离线性。这些结果与Hourston和Hughes报道的各种相容和不相容共混物的声速测量结果一致。超声速度的变化已经从共混物的形貌上得到了解释，并从扫描电子显微镜得到了进一步的证据。
The behaviours of solid compatible, poly(methyl methacrylate)-poly(vinyl acetate), and incompatible, poly(methyl methacrylate)-polystyrene, blends have been studied by ultrasonic velocity measurements. It has been found that, in the compatible blends, the ultrasonic velocity varies linearly with composition; it deviates from linearity in the incompatible blends. These results are in conformity with the results of sonic velocity measurements for various compatible and incompatible blends reported by Hourston and Hughes. The variation of ultrasonic velocity has been explained in terms of morphology of the blends, with further evidence from scanning electron microscopy.
