The morphology of polyacrylic acid nanogels was characterized by atomic force microscopy and nanogels with particle size of 20~60?nm were observed under conditions studied.The monomer concentration and the cross-linker concentration had influences on the microstructure and particle size of polyacrylic acid nanogels.The nanogels with a reinitiating ability and its particle size bigger than before were obtained through further polymerization initiated by benzophenone derivant BP-4.Also,the PAA-g-PNIPAM nanogels with particle size of 50~90?nm were prepared by further graft polymerization.
