Abstract
Abstract A composition having the structure <IMAGE> wherein -R' is -F or -Cl, each -R'', which may be the same or different, is independently selected from the group consisting of C1-C6 alkyl or hydroxyalkyl moieties and aryl moieties, and n is 1 or 2. These compositions are useful as co-monomers or end-cappers for the introduction of thermally reactive cross-linking sites into polymers.
