摘要：

We herein report a facile method to prepare the submicron-sized raspberry-like polystyrene/polyacrylonitrile particles with anisotropic properties and controllable structure via c-radiation-induced seeded emulsion polymerization under ambient pressure and at room temperature, in which the monodisperse crosslinked styrene-divinylbenzene-acrylic acid terpolymer (P(S-DVB-AA)) particles were used as seed particles and acrylonitrile (AN) as the second monomer. The influence of the weight ratio of polymer/monomer, the absorbed dose rate, the absorbed dose, and the dispersion medium on the morphology of the as-prepared particles was investigated. The final products were thoroughly characterized by Fourier transform infrared spectroscopy (FTIR), field-emission scanning electron microscopy, and transmission electron microscopy. The results showed that the raspberry-like particles could be fabricated in high yield. (C) 2010 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 48: 5198-5205, 2010
