A substantially anhydrous, acid-free, room temperature curable composition which comprises (A) an organic thermoplastic polymer containing at least two hydroxyl radicals which are directly bonded to non-carboxylic carbon atoms of said polymer; and (B) a hydrolyzable aminosilicon compound selected from the class consisting of aminosilicon compounds having the average formula [Figure] and mixtures thereof wherein: X is an alkoxy radical having 1 to 6 carbon atoms; R is a divalent alkylene radical having 1 to 4 carbon atoms; R1 is hydrogen or an alkyl radical having 1 to 4 carbon atoms, R2 is a radical selected from the group consisting of hydrogen, an alkyl radical having 1 to 4 carbon atoms and a silyl radical of the formula [Figure] wherein R, R1, and X are the same as defined above; and wherein R3 is a divalent alkylene radical having 2 to 4 carbon atoms; a has a value of 0 to 2 and t has a value of 0 to 4; and wherein said composition contains about 5 to 50 parts by weight of said hydrolyzable aminosilicon compound (B) per 100 parts by weight of said organic polymer (A).
