The traditional melt radical functionalisation of isotactic polypropylene (iPP) with maleic anhydride (MAH) and peroxide affords functionalized samples with a severe decrease of the average molecular weight (MW) due to the β-scission reaction. In th

Polypropylene (PP) samples functionalized with Maleic Anhydride (MAH) were used as interfacial coupling agents during the preparation of PP based layered silicate nanocomposites (PP-LSN). To prepare these functionalized PP samples, butyl 3-(2-furyl)p

Grafting of polypropylene and its potential use as metal ion adsorption resin

Autor: Sylvain Augier, Serena Coiai, Lucía Pérez Amaro, Bernabé L. Rivas, Francesco Ciardelli, Elisa Passaglia

Publikováno v: Journal of Applied Polymer Science. 113:290-298

Polypropylene (PP) was modified by radical grafting of acrylic acid (AA) in the melt by using dicumyl peroxide (DCP) as initiator. To reach a high grafting degree (GD) without substantially modifying PP-chain structure, a few runs were carried out by

Organophilic Boehmite Nanoparticles by ATRP Methacrylates Polymerization: Synthesis, Characterization and Dispersion in Polypropylene

Autor: Serena Coiai, P. Narducci, Elisa Passaglia, Sylvain Augier, Francesco Ciardelli

Publikováno v: Journal of Nanoscience and Nanotechnology. 8:1803-1811

Boehmite nanoparticles covered with a polymer shell enhancing the organophilicity of the surface were prepared by physical adsorption of a polyelectrolyte atom transfer radical polymerization (ATRP) macroinitiator followed by graft-polymerization of

The occurrence of significant degradation by b-scission reaction is a severe drawback affecting the classical procedure of polypropylene (PP) functionalization in the melt with maleic anhydride (MAH) or derivatives and free radical initiators. The pr

In this work, we provide more insight into the rheological properties of functionalized polypropylene copolymers with modified architectures, which originate long-chain branching. The evaluation of the average distance between branches and the frac-
