The image created by Maria de Fátima Vieira Marques and colleagues shows PP/PA6 blend using the copolymer poly (L‐LA‐co‐ε‐CL) as a compatibilized agent. The blend shows a dispersed phase with large particles, yet less spherical shapes and a rough surface. The addition of the biodegradable copolymer to the mixture provided a slight improvement in the interfacial adhesion with a better wettability of the continuous phase in the dispersed phase, indicating a reduction in the interfacial tension between the two components of the mixture.

玛丽亚·德·法蒂玛·维埃拉·马克斯（Maria deFátimaVieira Marques）及其同事创建的图像显示，使用共聚物聚（L-LA-co-ε-CL）作为增容剂，共混了PP / PA6。共混物显示出具有大颗粒的分散相，但球形较小，表面粗糙。将可生物降解的共聚物添加到混合物中，界面粘合性略有改善，连续相在分散相中的润湿性更好，表明混合物两种组分之间的界面张力降低。DOI：10.1002 / app.50248
