The Molecular Mechanism of Adhesion Improvement of 3-Aminopropyltriethoxysilane in Glass Reinforced Nylon Modelcomposites
Chapter
Abstract
Selectively 13C-enriched 3-(3-13C)aminopropyltriethoxysilane ((3-13C)-APS) is used to investigate silane-polymer reactions and/or interactions in glassbead reinforced Nylon (PA-6) modelcomposites. With 13C MAS NMR and Pyrolysis GC/MS evidence is obtained for amide formation between -C00H PA-6 endgroups and -NH2 groups of APS and interpenetration of PA-6 chains into the poly-APS network.
