The cover image by Saori Nara and colleagues shows TEM micrographs of (56/14/30) PPS/EGMA/PPSU exhibiting superb toughening with increase of the tensile impact strength over five times compared to neat PPS. The PPSU phase appears white (a size of 0.2 – 2 mm), the PPS matrix gray, and the EGMA with EGMA‐PPS copolymers is black (a size of 0.05 – 0.2 mm). The copolymers are formed in situ during melt mixing at the interface between PPS and EGMA and were dispersed only in the PPS matrix. DOI: 10.1002/app.49994
