[Problem] To improve long-term storage stability of a polymerizable composition containing an organoborane and a polymerizable monomer. [Solution] Provided is a polymerizable composition which contains an organoborane (A), a polymerizable monomer (B) having no acid group, and a stabilization agent (C) for the organoborane (A), and which is characterized in that when the composition has been left standing still at 45°C for 48 hours, the ratio between the pre-still-standing viscosity and the post-still-standing viscosity (pre-still-standing viscosity/post-still-standing viscosity), as respectively measured using an E-type viscosimeter at temperature of 25°C and at a revolution speed of 50 rpm, is less than 100. |
