A polyether having molecular weight from 1,000 to 50,000, end-blocked with hydrolyzable silyl groups and represented by the general formula (P): <IMAGE> <IMAGE> +TR <IMAGE> where R1, R2, R6 and R7 individually represent a divalent hydrocarbon group, R4 represents a monovalent hydrocarbon group, R8 represents an alkyl group with 1 to 6 carbon atoms, X represents an aromatic or heterocyclic ring, a represents a number from 1 to 3, m represents a number from 10 to 500, n represents a number of 1 or greater is produced and utilized in room temperature curing compositions containing inorganic filler and curing catalyst. There is also disclosed a method for producing the above polyether by reacting polyoxyalkylene end-blocked with epoxy groups, dimercapto compound and organo silicon compound.
