Functionalization of ethylene‐propylene‐diene terpolymer via the alder ene reaction

Abstract: An ethylene‐propylene‐diene rubber (EPDM), containing 5 wt% 5‐ethylidene‐2‐norbornene, was functionalized with maleic anhydride through the Alder Ene reaction at temperatures above 200°C in a co‐rotating twin screw extruder. Characterization of the maleated product included FT‐IR, 1H and 13C NMR, and GPC. The degree of functionalization was determined by infrared analysis and by the mechanical properties of an ionic network formed by neutralizing the maleated rubber with zinc oxide. Increased temperature and m… Show more

“…The sulfonated copolymers show a new band at around 890 cm −1 indicating that, in accordance with previously reported data, part of the original endo double bond (CHRCR 2 ), at 840 cm −1 , may isomerize and form an exo double bond (CH 2 CR 2 ).…”

“…Over 1/3 of his articles mention catalysis as a keyword and most of this work has been dedicated to polymerization (Figure 5.3). As many as 8 of his articles mention maleic anhydride, which he applied to functionalize and rubber [112] and grafting it to natural rubber [113,114] . sing 330 articles and 16 conference proceedings.…”
