Abstract
In the last few years, a very wide range of oligocarbonate diols, oligomers of carbonic acid esters terminated on both sides with hydroxyl groups, have appeared on the chemical market. They are mainly used for the production of flexible segments in precious grades of polyurethanes used in biomedical engineering. Poly(carbonate-urethane) due to high resistance to oxidizing and hydrolytic agents is also an attractive material for the production of adhesives and coatings with increased resistance to weather conditions. This paper presents the current state of knowledge on the methods of synthesis and main producers of oligomerols with carbonate groups, methods of poly(carbonate-urethane) synthesis and examples of its commercial applications.
