The reliable and efficient counting of active sites in catalytic olefin polymerization has been realized by using acyl chloride as the quench-labeling agent. However, molar ratio to alkylaluminum cocatalyst must be larger than 1 order completely depress side reactions between quencher Al-polymeryl that is formed via chain transfer reaction. In this work, a tetrahydrofuran/thiophene-2-carbonyl (...

Chemical recycling of plastic waste has promise as a complementary technology to increase eco-efficiency plastics life cycles. Accumulation impurities in feed streams can affect sensitive compounds such the Ziegler–Natta catalyst systems commonly used produce polyolefins high density polyethylene (HDPE) and linear low (LLDPE). In poison study, influence impurities—more specifically NO N2O—on sy...
