摘要:
A chemical complex of Tc-99m with 1,2-dihydroxy-1,2-bis(dihydroxyphosphinyl)ethane is skeleton specific. The complex can be made by reducing pertechnetate ion and reacting the reduced technetium species with 1,2-dihydroxy-1,2-bis(dihydroxyphosphinyl)ethane. The complex is normally used in a biologically sterile, substantially isotonic aqueous medium as a skeleton imaging agent.
摘要:
N-(Substituted phosphinyl) polyamides and a method for their production are disclosed. The N-(substituted phosphinyl) polyamides are characterized by the recurring unit structure represented by the formula ##STR1## wherein A is in part hydrogen and in part a substituted phosphinyl radical. One method of producing the N-(substituted phosphinyl) polyamides is treating N-chlorinated polyamide with substituted phosphinyl compounds. The disclosed N-(substituted phosphinyl) polyamides exhibit excellent thermal stability fire resistance, good processability, high water absorption and permeability. The N-(substituted phosphinyl) polyamides are useful for making flame resistant textile materials.
