Title:

USE OF HYDROGEN PEROXIDE IN SOLID FORM TO MODIFY THE RHEOLOGY OF A THERMOPLASTIC POLYMER WHEN MELTED

Document Type and Number:

WIPO Patent Application WO/2019/092378

Kind Code:

A3

Abstract:

The invention relates to the use of at least one hydrogen peroxide in solid form to modify the rheology of a thermoplastic polymer when melted, specifically a polyolefin and particularly a polymer comprising at least one unit from propylene and, more particularly, polypropylene. The invention also relates to a method for modifying the rheology of a thermoplastic polymer when melted, specifically reducing viscosity when melted.
