چكيده لاتين :
At oscillatory rheometry method in linear viscoelastic region, storage and loss modulus vs.
frequency graph of ABS at molten state has two crossover points (COP). First COP increases
while TiO2 content arises up to 1.5% in Cristal 134 pigmented ABS samples. By arising TiO2 first
COP dramatically decreases because of agglomeration of the pigments. TEM micrographs approve
that agglomerates of Cristal 134 particles are formed above 1.5% content. Therefore, shifting of
first COP as a rheological parameter could be applied as a criterion to specify dispersion quality of
TiO2 particles in ABS matrix.
