| 摘 要： | 1. INTRODUCTION Hollow particles have been produced usually by the alkali swelling procedure (ASP), dynamic swelling method (DSM), and water-in-oil-in-water (w/o/w) emulsion polymerization 1]. Because particles can reserve various chemicals in their hollow, they could be used as reservoir and release material 2]. But almost all the work was to make hollow spheres. One kind of hollow particles, the bowl-shaped polymer particles have some advantages because of their special shape 3~6]…

| Abstract: | Poly(styrene-glycidyl methacrylate) particles having bowl-shaped hollow structures were synthesized by swollen seed emulsion polymerization. The PS emulsion synthesized through soap-free emulsion polymerization was swollen by toluene, and then the mixture of second monomers was added under polymerization condition. So a thin shell of poly(styrene-glycidyl methacrylate) cross-linked by triethylene glycol diacrylate was formed around the swollen PS particle. The bowl-shaped particles were obtained after the collapsing of the thin shell when the toluene emanated from the particles, but the shapes were effected by the degrees of cross-linking. The shape of the particles was observed by SEM. The release behavior of solvent from the particles was examined by TG. |
