摘要:
Heterocyclic aromatic polymers are rapidly formed by contacting one or more appropriate multifunctional aromatic monomers, such as a diaminobenzenediol, a terephthaloyl halide and/or an aminohydroxybenzoic acid, with a sulfonic acid, as the solvent, and a dehydrating agent.
摘要:
Novel humanized monoclonal antibodies, humanized antibody fragments, and derivatives thereof which specifically bind TAG-72 are provided as well as methods for their manufacture. These humanized antibodies are useful in the treatment of cancers which express TAG-72 as well as for diagnostic purposes, e.g., for in vivo imaging of tumors or cancer cells which express TAG-72.

摘要:
PBZ polymers are synthesized by the reaction of AA- and BB-monomers. The BB-monomer is conveniently synthesized and isolated as a phosphate salt having a uniform number of phosphate ions associated with each BB-monomer ion. Such high purity monophosphate and diphosphate salts can be obtained by precipitating the monomer from an aqueous acid solution by adjusting the pH balance or from a mixture of phosphoric acid and a volatile, polar, saturated organic liquid at a relatively low temperature.
摘要:
The invention is a process for making novel branched polybenzazole polymers and the polymers formed thereby. Novel compounds are also disclosed that are useful as branching agents in making the branched polybenzazole polymers. The branched polymers synthesized by the process can be formed into strong, light articles such as fibers and films.
