Development of Ziegler-Natta catalysts for the synthesis of polyolefins

, 2022
reservedLo scopo di questa tesi è la visione dello sviluppo di catalizzatori Ziegler-Natta per la sintesi di olefine. Vedremo cos'è un catalizzatore e nello specifico uno di tipo Ziegler-Natta, considerando i suoi componenti, gli effetti che hanno, l ...

Síntese de catalisadores Ziegler-Natta: algumas rotas e suas dificuldades Synthesis of Ziegler-Natta catalysts: some routes and their difficulties

Química Nova, 1997
The Ziegler-Natta catalyst and the polymerization thereof are systems which require careful handling and special treatment of chemicals. In spite of the use of inert atmosphere and dry chemicals, some Ziegler-Natta systems may present low activities or even may deactivate because of unsuitable handling.
