Abstract

La presente invencion consiste en un polímero a base de etileno que comprende hacer reaccionar una resma de polietileno con un derivado de alcoxiamina correspondiente a la formula: (R1) (R2)N-O-R3 donde R1 y R2 son cada uno de manera independiente uno del otro, hidrogeno, alquilo C4-42 o arilo C4-42, grupos de hidrocarbono sustituido que comprende O y/o N, y donde R1 y R2 pueden formar juntos una estructura anular; y donde R3 es hidrogeno, un hidrocarbono o un grupo hidrocarbono sustituido que comprende O y/o N. Los grupos preferidos para R3 incluyen alquilo -C1-19 arilo -C6-10 alquenilo -C2-19 -O-alquilo C1-19 -O-arilo C6-10 -NH-alquilo C1-19 -NH-arilo C6-10 -N-(alquilo C1-19)2. R3 contiene con mayor preferencia aun un grupo acilo. La resma resultante aumento la resistencia a la fusion con una mayor relacion de las viscosidades de estiramiento a 0,1 a 100 rad/s en comparacion con las resinas de polietileno sustancialmente similares que no se han hecho reaccionar con un derivado de alcoxiamina.
