对丙烯腈（AN）含量不同的聚酮（PK）与苯乙烯-丙烯腈（SAN）共混物进行了相容性研究。力学性能的测试表明了PK/SAN共混物的不相容性。玻璃化转变温度的变化和玻璃化转变宽度的加宽意味着PK/SAN共混物的非晶区的部分相容性。PK/SAN 48的C-2 O官能团的峰位移大于PK/SAN 40共混物。在形态学观察中，PK/SAN 48共混物的分散域似乎更精细，并且PK/SAN 48共混物在两相之间具有更好的边界粘附。PK/SAN混合物模拟的Flory-Huggins相互作用参数处于低水平，PK/SAN 48混合物显示出比PK/SAN 40混合物更低的值。这意味着PK/SAN聚合物共混物在无定形区域中是部分相容的。相容性水平倾向于随着SAN聚合物的AN含量增加而增加。© 2019 Wiley Periodicals，Inc.

Compatibility studies have been conducted for polyketone (PK) and styrene–acrylonitrile (SAN) blends in which SAN polymers have different acrylonitrile (AN) contents. Measurements of mechanical properties exhibit the immiscibility of PK/SAN blends. Glass transition temperature shifts and width broadening of the glass transition mean partial compatibility in the amorphous region of the PK/SAN blends. Peak shifts of the CO functional group are larger for PK/SAN48 than that of PK/SAN40 blend. In morphological observations, the dispersed domains appear more refined for the PK/SAN48 blend and the PK/SAN48 blend has better boundary adhesion between the two phases. The Flory–Huggins interaction parameters simulated for the PK/SAN mixture were at a low level and the PK/SAN48 blend showed lower values than the PK/SAN40 blend. This means that the PK/SAN polymer blend is partially compatible in the amorphous region. The level of compatibility tends to increase as the AN content of the SAN polymer increases. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci.2020,137, 48743.
