- Abstract
- Ene-grafting of maleic anhydride on polypropylene previously enriched in double bonds by beta-scission was promoted in order to obtain model grafted polypropylene. Ene-grafting was carried out in the presence of a radical-scavenger in order to limit at a minimum side-grafting and in presence of catalyst (SnCl2) in order to maximise the ene-grafting. Nevertheless, it does not lead to high grafting content. Ene-grafted PP confirms the single end-grafted succinic anhydride FTIR assignment at 1792 cm(-1) (C=O symmetric stretching) while a disubstitution is also observed leading to a shift to a 1784 cm-1 absorption band. This latter band was more generally assigned to interacting anhydride (C=O) instead of an assignment to the particular polyanhydride species (as previously assigned by our team [De Roover B, Sclavons M, Carlier V, Devaux J, Legras R, Momtaz A. J Polym Sci, Part A: Polym Chem 1995;33:829. [14]]). (c) 2005 Elsevier Ltd. All rights reserved.
