The emulsion polymerisation of styrene/2-ethylhexylacrilate/acrylic acid polymer particles with narrow particle size distribution is described. By syntheses, the weight ratio between styrene and 2-ethylhexylacrilate was varied in order to obtain particles with different viscous and viscoelastic properties. These parameters were measured with Carry - med S.L.C. rheometer 500. The results show that particles containing more 2-ethylhexylacrilate exhibit a higher viscosity level and higher storage and loss moduli than particles containing more styrene.
