Click chemistry within LDPE
May 20-25, 2018
Specialty LDPE copolymers provide some of the highest added value polyolefin applications and, in the quest to differentiate in an increasingly commoditized polyolefin environment, are of considerable interest to LDPE producers and other polyolefin players.1 In 2015, global specialty LDPE copolymers production was estimated around 6900 kT, from those EVA (Ethylene Vinyl Acetate) accounts for nearly 90 % of it.1 Other examples are EBA (Ethylene Butyl Acrylate), EVOH (Ethylene Vinyl Alcohol), COC (Cyclic Olefin Copolymer), MAH (Maleic AnHydride) grafted PE, … which all have their specific properties and are used in different kind of applications. All above mentioned commercial grades are made either by in reactor functionalization, copolymerization of ethylene and a monomer, or by post-modification, grafting of a monomer onto a PE backbone. A combination of both routes would give the advantage of producing one base grade; therefore, no changes in reactor settings are required and the properties of the polymer can be tuned by post-modification reactions.
