The results showed the addition of PPS did not decrease the thermal performance but decreases the heat deformation temperature of PPES/PPS blends. The crystallinity of PPS was hindered with the increasing of PPES contents, the crystal lattice flaws of PPS occurred and the perfect spherocrystal could not appear when the mass fraction of PPES was 80%. The annealing process was favorable to the increase of the heat deformation temperature and the formation of perfect spherocrystal of PPS.

热失重研究表明，在所组成范围内PPS的加入并未降低共混物的热性能，但使共混物的热变形温度有所降低；PPES的加入使PPS的结晶受到阻碍，当PPES质量分数达80%时，PPS产生了晶格缺陷，从而不能形成完善的球晶，退火过程有利於提高共混物的热变形温度，使PPS形成更完善的球晶。
