Resumen:
Two types of ethylene-octadecene copolymers, with different comonomer content, were modified by three different methods: treatment with an organic peroxide, gamma radiation and thermally activated oxygen. These modifications induce branching and crosslinking points which affect the molecular weight and the crystalline structure of the original copolymer The changes on the molecular structure and morphology were characterized by gel permeation chromatography and SSA technique using a conventional DSC.
