Ethylene Polymers,HDPE

Abstract

History of PEEarly Work. The history of HDPE (and polyolefins in general) actually began in the 1890s with the synthesis of "polymethylene" from the decomposition of diazomethane. Between 1897 and 1938, numerous reports of such polymers appeared in the literature (1-6). Catalysts such as unglazed china, amorphous boron, and boric acid esters were used for the decomposition. The empirical formula of such products was found to be CH 2 . Later reproductions of work (3,6) established Encyclopedia of Polymer Science and Technology.

“…Ethylene is an important biogenic emission, and inventories suggest that global emissions of ethylene to the atmosphere are dominated by biogenic sources (8–25 Tg), accounting for approximately 75% of the total emissions. , Anthropogenic sources include industrial emissions (ethylene is extensively used in the manufacture of polymers of wide applicability and also as precursor to many commodity chemicals) and also combustion sources including transport and biomass burning. , …”
