PURPOSE:To obtain a polyester capable of forming a rubber-like elastomer, having good adhesive property and extension ratio and rich in flexibility, by reacting a specific polyoxyalkylene with a primary or secondary amine and organosilicon compound in the presence of a monohydric primary alcohol. CONSTITUTION:A polyether, obtained by reacting a polyoxyalkylene, expressed by formula I (R<1> and R<2> are bifunctional hydrocarbon; n is 10-250) and having molecular terminals blocked with epoxy groups with a monofunctional primary amine expressed by the formula R<3>-NH2 (R<3> is monofunctional hydrocarbon) or bifunctional secondary amine expressed by formula II (R<4> and R<6> are monofunctional hydrocarbon; R<5> is bifunctional organic group) and an organosilicon compound, expressed by formula III (R<7> and R<9> are monofunctional hydrocarbon; R<8> is bifunctional hydrocarbon; R<10> is 1-6C monofunctional hydrocarbon; a is 1-3) and having amino group and hydrolyzable group in the presence of a monofunctional primary alcohol expressed by the formula R<11>-OH (R<11> is same as R<10>) and expressed by formula IV or V (m is a value to give 1,000-50,000mol.wt.).
