摘要： Narrow size distributed soap-free P(MMA-EA-MAA) latex particles with different crosslinking degree were synthesized by seeded emulsion polymerization of methyl methacrylate (MMA), ethyl acrylate (EA) and methacrylic acid(MAA) and voids and multihollow latex particles were obtained after undergoing alkali treatment. Influences of kind and amount of crosslinking agents on the polymerization, particle properties and particle morphology were investigated. Results showed that the monomer conversion increased slightly in the presence of the crosslinking agents. The size of particles decreased slowly as the amount of crosslinking agent increased,and the size distribution of the particles broadened at a higher amount of crosslinking agent. Divinyl benzene (DVB) was more effective than ethyl glycol dimethyl methacrylate (EGDMA) to make polymer crosslinked. During alkali treatment process, void latex particles can be obtained when no DVB or less than 0.5 wt% of EGDMA was used, while multihollow structure was generated when DVB or more than 1.0 wt% of EGDMA was introduced. The volume expansion of the particles decreased with increasing the amount of crosslinking agents.
