摘要：

Poly(methyl methacrylate)s (PMMAs) containing a terminal hydroxy group or multiple hydroxy groups as pendants were grafted to multiwalled carbon nanotubes (MWNTSs) by esterification in toluene at 100 degrees C. The recovered polymer with a low level of MWNTs and the PMMA-g-MWNTs with up to 12 wt.-% grafted polymer were characterized using spectroscopic, microscopic, and thermogravimetric analyses. The percentage of polymer present in the PMMA-g-MWNT samples is very low based upon the concentration of the acid groups in the tubes.
