Synthesis of high thermal stability Polypropylene copolymers with pyrrole functionality

Functionalization of polyolefins has been proven to be a promising way fine-tune their properties, among which, improved thermal stability is crucial for high performance in end-use applications. However, it still remains academia, as some important issues need resolved this methodology move towards industrial scale-up, the most them being development one-step processes. This work focuses specifically on single-step functionalization route synthesis and thermo-oxidative polypropylenes. The Polypropylene (PP) bearing N-alkyl groups by copolymerization via metallocene catalysis studied. copolymers are found exhibit stability, whose origin appears based, not only radical scavenging activity moieties, but also associated crosslinking that takes place under processing conditions. Some exploratory results from solid-state 13 CNMR analysis provide support mechanism, involving coupling between benzyl-like pyrrolyl species. • A process preparation self-crosslinkable Polypropylene.
