权利人:BASF SE
摘要:A process for preparing a thermoplastic polymer involves reacting at least components (a) to (b), in the presence of a catalyst composition (c). Component (a) is an isocyanate composition containing at least one uretdione diisocyanate (a-i), and component (b) is an epoxide composition containing at least one diepoxide (b-i). The catalyst composition (c) contains at least one ionic liquid (c-i), preferably selected from 1-ethyl-3-methyl imidazolium bromide, 1-benzyl-3-methyl imidazolium chloride. 1-butyl-1-methylpiperidinium chloride, 1-ethyl-2,3-dimethylimidazolium bromide, 1-(2-hydroxyethyl)-3-methyl imidazolium chloride, butyl-1-methylpiperidinium acetate, or mixtures of two or more thereof. A thermoplastic polymer obtained or obtainable from the process is useful for the preparation of a fibre or a molded article or as a modifier for another thermoplastic material.

标 题 :Chloroquine drug compositions and methods for their synthesis
发明人:KOSAK KENNETH M
权利人:KOSAK KENNETH M
摘要:This invention discloses compositions of chloroquine-coupled active agents, including methods for their preparation. The prior art has shown that chloroquines given as free drug in high enough concentration, enhances the release of various agents from cellular endosomes into the cytoplasm. The purpose of these compositions is to provide a controlled amount of chloroquine at the same site where the active agent is delivered, thereby reducing the overall dosage needed. n The compositions comprise a chloroquine substance coupled to an active agent directly or through a variety of pharmaceutical carrier substances. The carrier substances include polysaccharides, synthetic polymers, proteins, micelles and other substances for carrying and releasing the chloroquine compositions in the body for therapeutic effect. The compositions can also include a biocleavable linkage for carrying and releasing active agents for therapeutic or other medical uses. The invention also discloses carrier compositions that are coupled to targeting molecules for targeting the delivery of chloroquine substances and active agents to their site of action.
