本文介绍了由不饱和聚酯树脂基体和橡胶颗粒组成的聚酯树脂共混物的制备方法。用透射电子显微镜（TEM）观察了共混物的形态，用差示扫描量热法（DSC）和动态力学热分析（DMTA）研究了共混物的热性能。结果表明，制备的纳米粒子的粒径和形貌得到了很好的控制。DMTA的结果表明，没有减少基体的Tg，而改性材料的剪切模量被认为是低于基体材料。
Abstract The preparation of polyester resin blends consisting of an unsaturated polyester resin matrix and rubbery particles comprising three radially-alternating glassy and rubbery layers is described. The morphology of the resin blends was examined by transmission electron microscopy (TEM) while thermal properties were investigated by differential scanning calorimetry (DSC) and dynamic mechanical thermal analysis (DMTA). The results show that the particles were prepared with good control of particle size and morphology. DMTA results showed no reduction in the Tg of the matrix whilst the shear modulus of modified materials was found to be lower than that of the matrix material.
