Développées de b, c et d.
exercice n°6:
on réalise l'analyse d'un polymère obtenu par polyaddition. on constate qu'il contient, en
masse, 73,2% de chlore, 24,8% de carbone et 2% d'hydrogène.
1 quelle est la composition en masse du monomère m?
2 le polymère a une masse molaire moyenne de 121000 g. mol" et un degré de polymérisation
moyen de 1250. donner la formule brute de m.
3-indiquer toutes les formules développées possibles pour m.
6c
4-donner, dans chaque cas, le motif et le nom du polymère.
