Herein, the synthesis and characterization of a new aliphatic biodegradable copolyester named PBS/PBDL (poly(butylene succinate-co-butylene dilinoleate)) is reported. Surfactant-free, narrowly distributed, nanosized spherical particles (RH < 60 nm) have been produced from the biodegradable material by applying a single-step nanoprecipitation protocol. Their structure was characterized in detail by employing a variety of scattering techniques and transmission electron microscopy (TEM). Combined SLS and DLS measurements suggested that the nanoparticles comprise a porous core conferring a non-compact characteristic. Their porosity enables water to be entrapped which is responsible for their pronounced stability and relatively fast degradation as followed by size exclusion chromatography (SEC).
