Abstract
Un método para aumentar la estabilidad de burbujas de una resina de polietileno de alta densidad bimodal de alto peso molecular necesitada que lo necesita, el método comprende someter la resina de polietileno de alta densidad bimodal de alto peso molecular necesitada a una cantidad determinada de adaptación al oxígeno de la resina para aumentar independientemente tanto el módulo de almacenamiento de masa fundida de la resina G' (a G" = 3000 pascales) como la relación de viscosidad compleja SH1000 y, por lo tanto, hacer una resina de polietileno de alta densidad bimodal de alto peso molecular con adaptación al oxígeno que tiene un aumento específico en la estabilidad de burbujas. El método usa una cantidad efectiva de adaptación al oxígeno molecular (O2) para lograr la adaptación al oxígeno que se desea. El método usa estas propiedades reológicas avanzadas de la espectroscopía mecánica dinámica, pero analiza los datos de una manera diferente que es más sensible a los cambios en la composición y las propiedades de la resina y, sin embargo, logra un régimen de resina que tiene un aumento específico en la estabilidad de burbujas.
