Abstract

Una composicion de polímero comprende el componente de polímero de etileno de bajo de peso molecular (BPM) y el componente de polímero de etileno de alto de peso molecular (APM) acoplados con una azida de polisulfonilo. Preferiblemente, el componente de polietileno de LMW y el componente de polietileno de HMW co-cristalizan en la composicion tal que exhiben un pico unico substancialmente unico en una curva de distribucion de espesor lamella (LTD=CDL). El polímero del etileno para el LMW y los componentes de polietileno de HMW pueden ser o copolímeros u homopolímeros de etileno. Preferiblemente, ambos componentes son un copolímero de etileno del mismo, o diferente, la composicion (esto es, con los mismos o diferentes comonomeros). Se describe un método de hacer una tubería que incluye escoger una composicion de polímero que tiene un pico substancialmente unico en la curva LTD=CDL. Son descritas también en el presente documento las composiciones que comprenden un polímero cromo-catalizado de etileno, acoplado con una azida de polisulfonilo.
