El presente trabajo de investigación tiene como objetivo establecer una línea base para el estudio de películas reticuladas de polietileno lineal de baja densidad empleando peróxidos orgánicos como agente reticulante. Para analizar el efecto que tiene la reacción de reticulación sobre la matriz de un polietileno lineal de baja densidad, se procesaron cuatro muestras de DOWLEX XZ89446 con 0; 0,025; 0,030 y 0,040% en peso de peróxido respectivamente, y luego se determinaron sus propiedades a través de los ensayos de índice de fluidez, resistencia al impacto, resistencia al rasgado, ensayo de tensión y resistencia a la penetración. Se determinó que la reacción de reticulación afe...
First settled in 1643, Throggs Neck-Pelham Bay lies along the west bank of Eastchester Bay in the Bronx. It was once an area of grand estates and farms and was home to some of the wealthiest people in America, including Collis P. Huntington and Catherine Lorillard Wolfe. Discover the history of the early residents of the community and its place in an ever-changing America in this unique and unprecedented pictorial collection. Throggs Neck-Pelham Bay offers a unique glimpse into the past, through carefully preserved images and a thoroughly researched text. Readers will delight in the memories of yesteryear and the images of a young and undaunted America. The images in this volume cover all of the communities included in the charter granted to John Throckmorton by the Dutch in 1642. Called Vriedlandt or "Land of Peace" by Dutch authorities, the area eventually fell prey to the burdens of war during the American Revolution.
