1. Introduction The main purpose of any manufacturer is the extension of durability for their own products. This goal is achieved by means of several procedures: crosslinking [1,2], compounding [3,4], preparation of nanocomposites [5,6], and stabilization by antioxidants [7,8]. All of these procedures are based on the availability of polymer materials for molecular and morphologic reconstruction, starting from the recombination of fragments.
