摘要: To study the effect of dispersed poly(butadiene-co-acrylonitrile) (NBR) rubber size on physical properties poly(styrene-co-acrylonitrile) (SAN)/NBR blends, SANs with various melt viscosities and acrylonitrile (AN) contents were examined. The NBR, whose AN content is 30 wt %, was reduced as viscosity SAN matrix increased or in range 19–32 %. As increased, damping peak NBR phase moved to a higher temperature, reduced, lower temperature. Higher values impact strength elongation at break yield behavior low shear rate observed finer dispersion NBR. © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 73: 935–941,
