The study was conducted in three stages. First, PC was blended separately with acrylonitrile\u2013butadiene\u2013styrene (ABS), acrylonitrile\u2013styrene\u2013acrylate (ASA), and styrene\u2013butadiene\u2013styrene (SBS) over a range of compositions to compare their effects on mechanical performance. A representative PC\/ASA formulation was then selected to evaluate the effect of maleic anhydride-grafted ABS (ABS-g-MAH). Finally, poly(methyl methacrylate) (PMMA) was incorporated into the selected PC\/ASA formulation to form a ternary PC\/ASA\/PMMA system, in which the effect of ABS-g-MAH was further examined. Component identity and loading produced distinct mechanical trade-offs: ABS and ASA progressively reduced strength, stiffness, and elongation at break, whereas SBS better preserved tensile deformation capacity and flexural strength despite reduced stiffness. ABS-g-MAH substantially enhanced ductility and impact resistance in both selected systems, while its effects on stiffness, dynamic mechanical behavior, and thermal properties depended on blend composition and loading. Selective-etching scanning electron microscopy further revealed finer and more uniformly distributed phase morphologies after ABS-g-MAH addition. Overall, the results demonstrate that component selection establishes the underlying performance profile of PC-based blends, while compatibilizer addition provides a further means of adjusting morphology and property balance in a formulation-dependent manner. These findings provide a practical framework for tailoring PC-based engineering blends toward different performance requirements.<\/jats:p>","DOI":"10.3390\/polym18192339","type":"journal-article","created":{"date-parts":[[2026,9,25]],"date-time":"2026-09-25T08:09:02Z","timestamp":1790323742000},"page":"2339","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Tailoring the Performance Profiles of Polycarbonate-Based Engineering Blends Through Formulation and Compatibilization"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-7566-7590","authenticated-orcid":false,"given":"Ruogu","family":"Tang","sequence":"first","affiliation":[{"name":"Department of Animal & Food Sciences, College of Agriculture & Natural Resources, University of Delaware, Newark, DE 19713, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Wu, C., Xu, F., Wang, H., Liu, H., Yan, F., and Ma, C.
