Abstract: | The physical properties of nylon 6/poly(acrylonitrile-butadiene-styrene) terpolymer (ABS) blends using a maleated polybutadiene
(denoted PB-g-MA) as compatibilizer were investigated. The morphology results reveal that ABS domain sizes decrease with an
increasing compatibilizer content, suggesting the good interaction between the nylon 6 matrix and the ABS dispersed phase.
Cooling conditions and compatibilizer contents strongly affect the crystalline structure of nylon 6, as determined from X-ray
diffraction and non-isothermal crystallization thermal analyses. The coexistence of α- and predominantly γ-form crystals for
the 10 phr compatibilized blends was observed. Isothermal crystallization kinetics suggests that the introduced compatibilizer
impeded the growth rate of the crystals, especially for the higher compatibilizer content. The compatibilizer was beneficial
in enhancing the thermal stability of the blends. |
