Abstract

<p>Un método para controlar la deposición de pegajosidad o adherencias, en los procesos de elaboración de pulpa y de papel, que comprende agregar a la pulpa de fibras o al caldo, un aditivo que comprende un siloxano órgano-modificado que comprende unidades de la fórmula: [R1aZbSiO(4-a-b)/2]n en la cual cada R1 es seleccionado independientemente desde un átomo de hidrógeno, un grupo alquilo, arilo, alquenilo, aralquilo, alcarilo, alcoxi, alcanoiloxilo, hidroxilo, grupo éster o éter, <em>y </em>cada Z es independientemente seleccionados desde un grupo alquilo substituido con una amina, amida, carboxilo, éster, o un grupo epoxi, o preferiblemente a lo menos uno o más grupos -R2-(OCpH2p)q(OCrH2r)s-R3; en donde n es un entero mayor que 1; a y b son independientemente 0, 1, 2 o 3; R2 es un grupo alquileno o un enlace directo; R3 es un grupo como es anteriormente definido para R1 o Z; p y r son independientemente un entero desde 1 hasta 6; q y s son independientemente 0 o un entero de forma tal que 1 ≤ q + s  ≤ 400; y en donde cada molécula del siloxano órgano- modificado contiene a lo menos un grupo z. El siloxano órgano modificado es preferiblemente un polidimetilsiloxano linear coronado de termino hidroxilo o alquilo, en donde 5 a 18 por ciento en moles de átomos de silicio son substituidos por grupos z de la formula -R2-(OCpH2p)q(OCrH2r)s-R3,  en donde p es 2, r es 3 y q y s son independientemente 10 hasta 20, R2 es un grupo alquileno que tiene desde 1 hasta 6 átomos de carbono o un enlace directo, y R3 es un átomo de hidrógeno o un hidroxilo, alcoxi, o grupo éster o <em>éter.</em></p>
