PROCESS FOR IMPROVING THE MECHANICAL RESISTANCE AND THE COLOR CHANGE RESISTANCE OF A STABILIZED PROPYLENIC POLYMER, TREATED BY HIGH-ENERGY RADIATIONS AND PRODUCT OBTAINED

摘要

THE INVENTION RELATES TO POLYMER CHEMISTRY. /P P IT RELATES TO A PROCESS FOR IMPROVING THE MECHANICAL RESISTANCE AND RESISTANCE TO COLOR CHANGE OF A PROPYLENIC POLYMER TREATED BY A HIGHLY ENERGY RADIATION. /P P THE PROCESS CONSISTS OF INCORPORATING A PHENOLIC ISOCYANURATE IN THE POLYMER AS A STABILIZING AGENT, IN CONJUNCTION WITH A THIOSYNERGIC AGENT AND PREFERABLY A STEARATE.
