摘要：

Nanotubes of natural halloysite (HNTs) were used as a solid support for the heterogeneous atom transfer polymerization of methyl methacrylate (MMA) into poly(methylmethacrylate) (PMMA) using adsorbed CuBr-[1,1,4,7,10,10-hexamethyltriethylenetetramine] (CuBr-HMTETA) and CuBr-[3-(2-aminoethylamino)propyltrimethoxysilane] (CuBr-AEAPTS) as catalysts. CuBr-AEAPTS supported on HNTs proved to mediate a living polymerization of MMA, demonstrated by (i) an increase in the number-average molecular weight (M(n)) with the increase of conversion, (ii) relatively low polydispersity indexes (PDI), and (iii) linear first-order rate plots. The presence of HNTs; had a strong effect on the polymerization rate. (C) 2008 Elsevier Inc. All rights reserved.
