In this paper, the hollow polymer nanolatex microspheres with uniform size and good monodisperse made by in-situ polymerization with the method of encapsulation non-solvent,and the effect of crosslinking monomer (DVB) dosage in the shell on the morphology and opacity of the hollow polymer nanolatex microspheres were investigated by the characterization methods of particle size analysismeter, viscosity meter, acid value analysis, SEM, TEM and UV-Vis spectrophotometry. The results show that under the other conditions and MAA dosage of the shell unchanged, when the crosslinking monomer dosage of the shell was less than 15wt%, with the reduce of the crpsslinking monomer dosage in the shell, the strength of the shell of the hollow polymer nanolatex microspheres trends decrease, when pore-swelled, the hollow polymer nanolatex microspheres were easily cracked and collapsed; when the dosage was greater than 20wt%, with the increase of the crosslinking monomer dosage in the shell, the strength of the shell and particle size of the hollow polymer nanolatex microspheres trends increase and decrease respectively, it becomes difficult to swell; when the dosage is between 15-20wt%, the dry film of the emulsion containing the hollow polymer nanolatex microspheres obtained the the optimal opacity performance.
