Abstract

La presente invención divulga nuevas formulaciones de adhesivos termofusibles que comprenden, como componente polimérico principal, al menos una composición de polímero de metaloceno buteno-1 isotáctico, que tiene una baja viscosidad, y que tiene una composición bimodal, obtenida directamente durante la polimerización, en dos etapas de reacción consecutivas y separadas. Además, dichos termofusibles comprenden además menos del 5% en peso de al menos un modificador de viscosidad que no es sólido a temperatura ambiente. Tal nivel inusualmente bajo de dichos aditivos permite sorprendentemente alcanzar niveles sustancialmente mejorados tanto de alta adhesividad como de cohesión, como lo muestran los resultados excepcionalmente buenos en la prueba de tiempo de suspensión. En una modalidad de la presente invención, las formulaciones de adhesivos termofusibles divulgadas en el presente documento también comprenden menos del 5% en peso de una cera de polietileno o de una mezcla de ceras de polietileno, que se caracterizan preferiblemente por una estructura altamente lineal/no ramificada y por un índice de polidispersidad excepcionalmente bajo. La presencia de tales ceras de polietileno tan peculiares, que son parcialmente incompatibles con la composición del polímero de buteno-1, permite usar las formulaciones termofusibles divulgadas incluso en presencia de sustratos fibrosos o perforados, deteniendo completamente y evitando el fenómeno muy negativo conocido como traspaso.
