Abstract

Se describe un macromonomero de la formula I: en donde n es cero o cuando menos 1.0; Q es un grupo polimerizable; B puede ser igual o diferente, y es un bloque difuncional de un peso molecular en la escala de 100 a 8,000, y en donde cuando menos un B es un residuo de un polímero o copolímero difuncional en donde B tiene un peso molecular de 248 a 8,000, en cual comprende unidades de repeticion de silicona de la formula II: en donde R1 y R2 pueden ser iguales o diferentes, y se seleccionan a partir del grupo que consiste en hidrogeno, alquilo, alquenilo, alquinilo, arilo, haloalquilo, haloalquenilo, haloalquinilo, haloarilo, heterociclilo, y haloheterociclilo; L es un grupo de enlace difuncional; y T es un grupo terminal. El macromonomero se puede utilizar de preferencia en la produccion de lentes de contacto.
