CA 2381335

Disclosed is an intercalant compound having formula (I): wherein R1 is H or a C1-C4 alkyl, n is 2-17, and R2 is a radical selected from the group consisting of X, COOR3, CN, NR2, and NR2.HX, wherein R3 is R, NR2, NR2.HX or a monovalent metal cation, the R groups, the same or different from each other, being H or a linear or branched C1-C4 alkyl; and X being F, C1, Br or I. Further disclosed are clay materials intercalated with at least one compound of formula (I) and nanocomposites comprising an alpha-olefin polymer material and, dispersed in the matrix of the olefin polymer material, a clay material intercalated with at least one intercalant compound of formula (I).

L'invention concerne un composé intercalant de la formule (I): où R?1¿ représente H ou alkyle C¿1?-C¿4?, n est compris entre 2 et 17, et R?2¿ représente un radical sélectionné dans le groupe composé de X, COOR?3¿, CN, NR¿2?, et NR¿2 ?HX, où R?3¿ représente R, NR¿2?, NR¿2 ?HX ou un cation métallique monovalent, les groupes R, identiques ou différents les uns des autres, représentent H ou un alkyle C¿1?-C¿4? linéaire ou ramifié; et X représentant F, Cl, Br ou I. L'invention concerne également des matières argileuses intercalées avec au moins un composé de la formule (I) et des nanocomposites comprenant un polymère d'alpha-oléfine et, dispersée dans la matrice du polymère d'oléfine, une matière argileuse intercalée avec au moins un composé intercalant de la formule (I).Formule (I)
