Abstract

Procedimiento para la obtención de polisiloxanos modificados con policarbodiimida, donde el polisiloxano y el policarbodiimida como fases diferenciales se encuentran una en otra, en caso dado con enlace parcial químico y/o físico, caracterizado porque el policarbodiimida se produce por reacción de isocianatos de fórmula general OCN-R''-NCO donde R'' significa un resto alquileno o arileno, en caso dado también sustituido con grupos NCO, preferentemente con hasta 24 átomos de carbono, en presencia de un catalizador de carbodiimidización, en sí conocido, y en órgano polisiloxano.
