    摘要: Core-shell tecto(dendrimers) useful in biomedicine, pharmaceuticals, personal care products, and in other ways analogous to the known uses for dendrimers, hypercomb branched polymers, and other dendritic polymers are the reaction product of a core dendritic polymer molecule having a plurality of terminal functional groups of a first type which are not reactive with each other, and a plurality of shell dendritic polymer molecules having a plurality of terminal functional groups of a second type which are not reactive with each other, but which are reactive with the terminal functional groups of the first type. Each of the shell dendritic polymer molecules is chemically bonded to the core dendritic polymer molecule by a reaction of at least one of the terminal functional groups of the second type with at least one of the terminal functional groups of the first type.

    摘要: An analytical method for analysis of precipitation of a soluble sample comprises the steps of: (a) providing a sample (14) in solution (24); (b) precipitating (30) the sample from the solution while intermittently measuring (36) the concentration of sample remaining in the solution; and (c) based on the results of step (b) calculating the composition distribution (44) of the sample.
