    摘要: The present invention relates to thiol-ene curing compositions, which cure upon exposure to ultraviolet (UV) light and/or heat. The compositions include components having alkenyl (or “ene”) functionality and components having thiol functionality, which undergo thiol-ene curing. The compositions also include a cure system. More specifically, in some embodiments, the curable compositions include a vinyl polymer bearing alkenyl or thiol terminal functional group(s) and a cross-linking agent having the opposing functionality, i.e., thiol cross-linking agents with alkenyl-terminated vinyl polymers and vinyl cross-linking agents with thiol-terminated vinyl polymers. Also provided are methods of making and using the compositions, such as for sealants for in-place gasketing applications.

    摘要: The present invention relates to compositions of matter corresponding to the formula: ##STR1## wherein R.sub.1 through R.sub.4, inclusive, are independently selected from a hydrogen atom, a linear or branched alkyl or alkoxy group having from 1 to about 8 carbon atoms, an alkenyl group having from 2 to about 8 carbon atoms, amino, cyano or R.sub.1 and R.sub.1, R.sub.1 and R.sub.2, R.sub.2 and R.sub.3 or R.sub.3 and R.sub.4 may together form part of a cyclohydrocarbyl ring. The subject 9,9-bis(3,4-dicarboxyphenyl)fluorene dianhydrides demonstrate utility as reactants in the preparation of polyimides used in the fabrication of membranes for separating gaseous mixtures into their respective components.
