Diels-Alder reactions to attach 1,2-dihydro-4-chloroformylbenzocyclobutene end-capped polymers (12) onto EPDM have been performed in a Brabender batch mixer at high temperatures (250-280 [degrees] C).
5) that BCI-MX, due to its unique chemical structure, reacts with the dienes/trienes formed along the polymer backbone as a result of reversion via the classical Diels-Alder reaction mechanism to form new thermally stable, long and flexible carbon-carbon crosslinks which compensate for the loss of sulfidic crosslinks occurring during reversion (figure 1).
When Corey first reported a laboratory synthesis of prostaglandins 21 years ago, chemists had no way of controlling the orientation at which these two reactants would approach each other during this step, known as a Diels-Alder reaction.
