Polymer Depressor Additives: Synthesis, Microstructure, Efficiency

Depressor additives, an important class of functional polymers widely used in petrochemistry, are discussed. The consideration is based on the comparison of the synthetic approaches to the basic structural classes of polymer depressor additives and the characteristics of different polymers. The mechanisms of the depressor additive action related to their molecular structure and the advanced lines in the chemistry of polymers demonstrating the depressor effects are analyzed. In the bibliography of the review, the most important publications within the last 15 years are presented.
