Abstract

The rheology, thermal and dynamic mechanical properties and phase morphology of blends of polyamide 6 with natural rubber (NR) are explored. The objective was to investigate in situ formation of a graft copolymer between NR and polyamide 6 during processing. Addition of maleic anhydride (MA) to the rubber was done prior to blending with polyamide 6. During processing MA can react with both NR and polyamide 6 leading to the graft copolymer formation. Molau test was used to confirm this graft copolymer formation. Rheology and thermal properties as well as dynamic mechanical analysis also indicated the graftization. Blend morphology analysis showed a significant reduction in particle size as the MA was added to the rubber. (C) 2000 Elsevier Science Ltd. All rights reserved.
