Elaboration et caractérisation des hybrides "organiques-inorganiques" du polyméthylhydrosiloxane réticulé par des oléfines synthétisées
Written by sctunisie no commentsReactions of allylbromide with benzene-1,2,4,5-tetracarboxydiimide (BTCD) and hydroquinone in different solvents are carried out. They lead to the formation of N,N'-diallylbenzene-1,2,4,5-tetracarboxydiimide (N,N'DBTCD) and 1,4-bis(prop-2-enyloxy)benzene (BPEB) that have been characterized by infrared, 1H NMR and 13C NMR, The polymethylhydrosiloxane (P.M.H.S) is modified by these prepared organic olefines. The mixtures of reactants under appropriate proportions and conditions, lead to the formation of polymeric gels. These materials have been characterized by Infrared, 1H NMR, 13C NMR and Scanning Electronic Microscopy (S.E.M).
