| Abstract: | Seed latex S consisting of styrene (St) and ethyl acrylate (EA) was firstly prepared by batch process, then a serise of St-EA-AA(acrylic acid) terpolymer latexes containing different amount of divinyl benzene(DVB) as crosslinking agent were synthesized by continuous seeded emulsion polymerization in the absence of emulsitiers, and the composite latexes were then treated by alkali and acid subsequently at 70℃ respectively for 2h and 1h. Particle size and morphologies were characterized by TEM using phosphotunstic acid as staining agent. Experimental results showed that the crosslinking degree had great effect on the formation of the multihollow structure in particles. |
