A small amount of cyano groups in poly(styrene-co-acrylonitrile) (SAN) was converted to oxazoline groups through reaction with 2-aminoethanol. Reactive melt blending of oxazoline-containing SAN and acidified multiwalled carbon nanotubes (MWCNTs) leads to the grafting of polymer chains onto MWCNTs arising from reactions between oxazoline and carboxylic acid groups. Spectroscopic; thermal and microscopic techniques confirmed the successful grafting of SAN onto MWCNTs. This method is comparatively simpler and greener than a previously reported method; and can be adopted to graft other acrylonitrile-containing polymers onto MWCNTs. © 2008 Elsevier Ltd.
