Abstract

UNA ESTRUCTURA DE PELICULA POLIMERICA MULTICAPA, ORIENTADA BIAXIALMENTE, OPACA, DE COEFICIENTE DE ROZAMIENTO SUPERFICIAL REDUCIDO. LA ESTRUCTURA DE DICHA PELICULA COMPRENDE: (A) UNA CAPA DE NUCLEO DE MATRIZ POLIMERICA, CON UNA PRIMERA SUPERFICIE Y UNA SEGUNDA SUPERFICIE, EN LA CUAL ESTA SITUADO UN ESTRATO CON HUECOS; DENTRO DE UN NUMERO CONSIDERABLE DE HUECOS ESTA SITUADA, AL MENOS BASICAMENTE, UNA PARTICULA INICIADORA DE HUECOS, ESFERICA, QUE ES DISTINTA EN FASE E INCOMPATIBLE CON EL MATERIAL DEL NUCLEO, SIENDO EL ESPACIO VACIO OCUPADO POR LA PARTICULA CONSIDERABLEMENTE INFERIOR AL VOLUMEN DEL HUECO. LA CANTIDAD DE HUECOS EN EL NUCLEO ES TAL, QUE PRODUCE UN GRADO SIGNIFICATIVO DE OPACIDAD. (B) AL MENOS UNA CAPA INTERMEDIA POLIMERICA, TERMOPLASTICA, QUE TIENE UNA PRIMERA SUPERFICIE Y UNA SEGUNDA SUPERFICIE, ADHIRIENDOSE LA SEGUNDA SUPERFICIE DE LA CAPA INTERMEDIA A AL MENOS LA PRIMERA SUPERFICIE DE LA CAPA DEL NUCLEO, ESTANDO FORMADA DICHA CAPA INTERMEDIA POR UNA MEZCLA QUE COMPRENDE EL POLIMERO TERMOPLASTICO, UN AGENTE DE DESLIZAMIENTO MIGRATORIO Y UN AGENTE ANTIESTATICO MIGRATORIO; Y (C) UNA CAPA FINA TERMOPLASTICA SIN HUECOS, QUE SE ADHIERE A LA PRIMERA SUPERFICIE DE LA CAPA INTERMEDIA, DENTRO DE ESTA EL AGENTE DE DESLIZAMIENTO Y EL AGENTE ANTIESTATICO MIGRAN HACIA LA SUPERFICIE EXTERIOR DE LA CAPA FINA Y SON EFECTIVOS PARA REDUCIR EL COEFICIENTE DE ROZAMIENTO SUPERFICIAL DE LA MISMA.
