Preparation of core (PBA/layered silicate)–shell (PS) structured complex via γ-ray radiation seeded emulsion polymerization

In order to improve the impact strength of PS matrix dramatically and keep its high tensile strength at the same time, a novel core–shell structured complex was prepared by γ-ray radiation seeded emulsion polymerization. The core is made of poly (butyl acrylate) (PBA) and the intercalated or exfoliated organophilic montmorillonite (OMMT), while the shell is PS. The prepared core (PBA/OMMT)–shell (PS) structured complex combines the advantage of the strengthening of silicate layers and the toughening of elastomer in plastic matrix. When the core (PBA/OMMT)–shell (PS) structured complex was blended in pure PS matrix, the impact strength of blend was dramatically improved and the tensile strength of PS remains high as well.
