From the author: The polymerization of acrylamide (AAM) onto calcium carbonate (CaC[O.sub.3]) particle surfaces induced by ultraviolet light and the properties of polyamide-6 (PA6) filled with the surface-treated CaC[O.sub.3] were studied. Electron spectroscopy for chemical analysis (ESCA), scanning electron microscopy (SEM), particle size distribution, impact strength and degree of polymerization measurements were determined. After AAM polymerization, a PAAM layer was formed on the CaC[O.sub.3] surface. This layer tightly banded the CaC[O.sub.3] particle and could not be washed away by acetone. A [N.sub.1s] peak was observed in the ESCA spectra of the treated CaC[O.sub.3] particles. The average particle size of the treated CaC[O.sub.3] increased compared to that of the original CaC[O.sub.3]. The interfacial interaction and impact strength of the treated CaC[O.sub.3]-filled PA6 were enhanced compared to those of the untreated CaC[O.sub.3]-filled PA6. Polym. Eng. Sci. 44:1277-1282, 2004.
