FIELD: chemistry.
SUBSTANCE: invention relates to synthesis of organosilicon compounds in which silicon is bonded to oxygen-containing groups. Disclosed are oligosiloxanes with hydrophilic and hydrophobic branches of general formula (I), where n equals 9, m equals 500–540, as a modifier for siloxane rubber. Method for production thereof is also disclosed.
(I).
EFFECT: disclosed oligosiloxanes significantly improve physical and mechanical properties of sealants based on siloxane-modified rubber 60 modified with disclosed oligosiloxanes, and disclosed method of producing simplifies the process of producing modified siloxane rubber.
