A novel impact modifier for nylon 6

A new carboxylated styrene-butadiene rubber (CSBR) in ultrafine powder form was used to modify the properties of nylon 6. The nylon 6/CSBR blends possessed higher toughness than nylon 6/maleic anhydride-grafted polyethylene octene elastomer (POE-g-MAH) system. TEM micrographs revealed the fine dispersion of CSBR particles with a diameter of 150 nm. The effective toughening of nylon 6 with CSBR was attributed to the good interface, fine dispersion, and shear yielding.Materials Science, MultidisciplinaryPolymer ScienceSCI(E)EI18ARTICLE12867-87028
