(57) [Summary] [Problem] Low viscosity, good workability, sufficient curing speed, excellent weather resistance, heat resistance, water resistance, etc., high strength, high elongation (low elastic modulus). To provide a composition from which a rubber-like cured product can be obtained. (A) A silyl group-containing ethylene / α-olefin / non-conjugated polyene random copolymer rubber containing a hydrolyzable silyl group having a specific structure in a molecule, and (B) A rubber composition containing an organosilicon polymer is provided. |
