| description | Una composición que comprende: (i) una arcilla en capas, constituida por partículas laminares cuyos iones han sido intercambiados con un catión orgánico representado por la fórmula I en la que: (1) M es nitrógeno o fósforo, (2) R1 es un grupo alquilo lineal o ramificado que tiene por lo menos 8 átomos de carbono, (3) R2, R3 y R4 se seleccionan independientemente de hidrógeno o ligandos orgánicos u oligoméricos, (4) por lo menos uno de R2, R3 y R4 comprende un grupo óxido de alquileno que tiene 2 a 6 átomos de carbono o un grupo poli(óxido de alquileno), y (ii) por lo menos un agente de expansión para incrementar la distancia basal de la organoarcilla en capas, en el que el agente de expansión se selecciona del grupo formado por poli(caprolactona), poliepóxidos, poliestireno, poliacrilatos, policarbonatos, poliuretanos, polisulfonas, poliéteres, policetonas, poliamidas y poliésteres que comprenden restos de por lo menos un ácido dibásico y un glicol.
The present invention relates to a composition comprising a polymer having dispersed therein at least one layered clay material which has been cation exchanged with an organic cation salts represented by Formula I: wherein M represents either nitrogen or phosphorous; X- represents an anion selected from the group consisting of halogen, hydroxide, or acetate anions, preferably chloride and bromide; R1 is selected from the group consisting of straight and branched alkyl groups having at least 8 carbon atoms; R2, R3, and R4 are independently selected from straight or branched alkyl groups having 1 to four carbon atoms; and at least one expanding agent which is compatible with said polymer. Preferred polymers include polyesters. The compositions of the present invention show vastly improved platelet separation as evidenced by higher than previously reported basal spacing. |
