Abstract: | Summary Reactive monomers such as acrylic acid (AA), maleic anhydride (MA) and glycidyl methacrylate (GMA)
were grafted onto acrylonitrile-butadiene-styrene core-shell copolymer (ABS) by emulsion polymerization
method. These functionalized ABS were used to toughen PA6. FTIR and Molau tests showed that these monomers
were introduced onto ABS copolymers and compatibilization reactions took place between PA6 and the AA, MA
and GMA grafted ABS. TEM result showed that the modified ABS copolymer dispersed in PA6 matrix uniformly
and no obvious difference could be found between the different PA6 blends. However, mechanical test showed
that GMA and MA modified ABS achieved much better toughening effect than the AA grafted ABS copolymer due
to the stronger interfacial reactions. Fracture characterization indicated that PA6 toughened with GMA
and MA modified ABS showed higher Givalues according to the Vu-Khanh approach and
much obvious shear yielding in the deformed zone could be found. |
