    Abstract: The present invention provides radiation curable resin compositions having enhanced low temperature flexibility and to methods of using these compositions. The radiation curable resin compositions contain no or essentially no volatile organic components (VOCs), and find particular use as coating compositions. In particular, the radiation curable resin compositions of this invention comprise a vinyl dioxolane end-capped oligomer blended with a photoinitiator.

    Abstract: Processes for producing oriented films of semicrystalline thermoplastic polymers, such as polyimides, and films produced thereby are disclosed. One process includes partial crystallization or imidization, orientation and further crystallization or imidization. Another process includes rendering a film of semicrystalline thermoplastic polymer amorphous, orienting the film and introducing crystallinity.

    Abstract: Bis-ethynyl quinoxaline compositions are prepared by the condensation reaction of an aromatic diglyoxyl or dibenzil with an ethynyl-substituted aromatic ortho-diamine. The compositions are useful as polymerizable plasticizers for heterocyclic thermoplastic resins in the fabrication of composites. Polymerizable plasticizers are materials that remain fluid and act as a plasticizer during early stages of fabrication and then polymerize to a rigid resin.

    Abstract: Substituted phenyl-benzimidazo compounds are disclosed in which the phenyl group which is attached to the two position of the imidazo ring contains a carboxylic acid group, or derivatives thereof, para to the point of imidazo attachment. The benzimidazo is substituted in the 5,6 positions with amino groups or derivatives thereof. The compounds are particularly useful as AB-monomers in the preparation of poly [(2,6-imidazobenzimidazo)1,4-phenylene].
