WebbEthylene polymerization, Abstract An insoluble form of methylaluminoxane, also known as solid polymethylaluminoxane (sMAO), has been synthesized by the controlled hydrolysis of trimethylaluminum (TMA) with benzoic acid, followed by thermolysis. WebbWhen our breakthrough loop slurry process was formally introduced in 1961, it immediately revolutionized the production of high-density polyethylene. Today we are a world leader in polyethylene production and licensing, with more than 1,000 related patents and more than 80 licensed plants in 20 countries. MarTECH ® Loop Slurry Process
