Effect of Rubber Particle Size and Graft Ratio on the Morphology and Tensile Properties of ABS Resins

Abstract

Tensile properties and the phase morphologies of ABS resins with various rubber particle sizes and graft ratios of SAN are examined. Large rubber particles disperse well in ABS resins irrespective of the graft ratio. On the other hand, the graft ratio affects the dispersion state of the small rubber particle, particles with high graft ratio disperse well and those with low graft ratio tend to coalesce into large aggregates. These differences of the morphology strongly alter the deformation mechanism, such as craze formation and cavitation in the rubber particles. The effects of mixing of ABS resins with various graft ratio and particle size on the mechanical properties and phase morphology are also discussed.

Synthesis and characterization of ABS resin using in situ transferring from emulsion to suspension polymerization

“…The rubber particle size is generally recognized as another important factor affecting the impact resistance of ABS resins 9. For SAN, the critical size is in the range 80–700 nm, and more desirably 300–500 nm.…”

“…The SAN matrix may be produced during the grafting reaction or separately. These are the most popular processes for the preparation of ABS resins; other processes such as the continuous mass polymerization process5–9 and the suspension polymerization process10, 11 are also used sometimes.…”

Preparation and Properties of Fragrant Acrylonitrile-Butadiene-Styrene Composites

“…Over the past decades, ABS and the series of related composites have been studied extensively [1][2][3][4][5][6][7][8][9] , they are a widely used commodity. However, their relative products do not continue to meet people's needs with improvement of living standards.…”
