FIELD: chemistry.
SUBSTANCE: invention relates to compositions of olefinically functionalised siloxane oligomers. Disclosed is a method for preparing a composition by reacting olefinically functionalised alkoxysilane with water in presence of a hydrolysis catalyst and a solvent to obtain a composition of olefinically functionalised siloxane oligomers with total content of chlorides of up to 100 mg/kg and average molecular weight from 410 to 750 g/mol. Also disclosed is a composition, obtained using disclosed method.
EFFECT: technical outcome is proposed method enables to obtain siloxane oligomers with low content of volatile organic components, having high stability during storage.
