The process of obtaining materials derived from polydimethylsiloxane (PDMS), polydimethylsiloxane (PDMS) material derivatives and their uses,

摘要

The process of obtaining materials of polydimethylsiloxane (PDMS) derived materials polydimethylsiloxane (PDMS) derivatives and their uses, the present invention proposes materials of PDMS - uretana (pdmsur) produced from a precursor, bis (ciclocarbonato) with segments of PDMS, by means of fixing Tion of carbon dioxide (CO2).This precursor is capable of reacting with amines, giving rise to a uretana - PDMS segmented without the use of isocyanates. The matrix of poliuretanas, with different terminations of chains, it is possible to incorporate other ligands, and obtained hybrid materials with different properties of industrial interest.The materials are capable of forming hydrophobic films on any metal surface and glass. Thus, these materials have applicability in industrial branch of adhesives, coating, sealant, biomaterials, among others.
