Summary Some principles at the basis of the potential interest of macromolecular drugs are defined. The main lines of a research on purposely tailored synthetic high polymers acting as precursors of non-macromolecular active substances are given. The chemical aspects of proper design of these polymers are discussed in detail.

Imaging of Humic Substance Macromolecular Structures in Water and Soils
Science, 1999Humic substances (HSs) are the natural organic polyelectrolytes formed from the biochemical weathering of plant and animal remains. Their macromolecular structure and chemistry determine their role in biogeochemical processes. In situ spectromicroscopic evidence showed that the HS macromolecular structures (size and shape) vary as a function of HS ...

Characterization of Water-Soluble Macromolecular Substances in Cloud Water
Journal of Atmospheric Chemistry, 2004In this contribution we present to our knowledge the first investigations of macromolecular, often called humic-like substances (HULIS) in cloud water samples and compare them with water-soluble extracts from atmospheric PM2.5, soils and waters to study its possible origin.

Deep eutectic solvent (DES) is a kind of solvent prepared by mixing hydrogen bond donors and hydrogen bond acceptors, and have become a hot topic in ecological civilization construction due to its low toxicity and sustainability. Its excellent properties such as low volatility, thermal stability and biodegradability make it stand out among many organic

MACROMOLECULAR STRUCTURES OF HUMIC SUBSTANCES
Soil Science, 1980ABSTRACTWe investigated humic substances by surface pressure and viscosity measurements at different pHs and neutral salt concentrations to elucidate their macromolecular configurations. We observed that such configurations were not unique; they varied with the changes in the medium.

Modification of Macromolecular Substances
2012The term “modification of macromolecular substances” is used for chemical and physical processes that are carried out after the actual synthesis, i.e., on the finished macromolecule. Chemical modifications are, for example, the conversion of ester side groups to hydroxy groups, chemical degradation and crosslinking reactions. Physical modifications are
