MOISTURE-CURABLE POLYMER SYSTEMS BASED ON MIXTURE OF POLYSILYLATED POLYESTERS Russian patent published in 2019 - IPC C08G65/333 C08G18/28 C08G18/50 C08G65/336 C08L101/10 

FIELD: chemistry.

SUBSTANCE: invention relates to polymer-curable polymer systems. Disclosed is a polysilylated polyether curable moisture-containing composition containing a mixture of polysilylated polyethers, which contains from 50 to 95 wt. % of one or more first polysilylated polyethers which do not contain carbamide groups containing on average two or more end hydrolysable silyl groups per molecule and having molecular weight from 4,000 to 20,000, and from 50 to 5 wt. % of one or more second polysilylated polyethers which do not contain carbamide groups containing on average 1.8 to 4 end hydrolysable silyl groups per molecule and having molecular weight from 1,000 to less than 400. Also disclosed are versions of the method of producing said composition and composition of an adhesive, sealant, putty or coating composition using said composition.

EFFECT: technical result is obtaining moisture-curable components of glue, sealant, putty and/or compositions of coatings with low viscosity, which enable to obtain articles with good strength characteristics.
