CROSS-LINKABLE POLYMER WITH TERMINAL SILANE GROUPS AND SEALING COMPOUND MADE FROM SAID POLYMER Russian patent published in 2010 - IPC C08G18/38 C08K5/54 

FIELD: chemistry.

SUBSTANCE: invention relates to production of eco-friendly sealing compounds, adhesives and coatings based on polymer resins with low content of volatile organic compounds. The invention discloses a cross-linkable polymer having terminal silane groups which contains a product of reacting a pre-polymer, having isocyanate terminal groups, and silane which contains several hydrolysable parts and at least one group having active hydrogen which can react with isocyanate, where after hydrolysis, the silane forms a low amount of volatile organic compounds compared to the amount of volatile organic compound which forms during hydrolysis of silane having an equivalent number of hydrolysable parts which are all hydrolysable alkoxy groups. The invention also discloses sealing compound, an adhesive or coating composition based on the disclosed polymer.

EFFECT: obtaining a silane-based cross-linkable polymer which can be used in production of silicon-containing polyurethane resins with low content of volatile organic compounds.
