Summary Crosslinked poly(methyl methacrylate/ethylene glycol dimethacrylate) P(MMA/EGDMA) nanoparticles (NPs) loaded with the antimicrobial agent methyl paraben (MP) were prepared by miniemulsion polymerization. The MP‐loaded NPs (i.e., ≤9.63 wt% MP) had an average size in the range of 108 to 145 nm. The NPs were subsequently incorporated in a low‐density polyethylene (LDPE) matrix, in the form of individual NPs and small aggregates (<1 µm), employing a twin screw extrusion process in the presence and absence of appropriate compatibilizers (i.e., montmorillonite clay (MMT), mesoporous silica (MCM‐41)). MP exhibited a sustained release profile from the P(MMA/EGDMA) (NPs) as well as from the LDPE matrix.
