A polymerizable composition includes an organoborane-base complex that is a complex of an organoborane and a base, a decomplexing agent that at least partially liberates the organoborane from the organoborane-base complex, a polymerizable thiol-containing component comprising at least one polymerizable thiol-containing compound having a plurality of thiol groups in which the sulfur atom of the thiol group is covalently bonded to carbon, a hydroperoxide, and a polymerizable ethylenically-unsaturated component comprising at least one polymerizable ethylenically-unsaturated compound having a plurality of ethylenically-unsaturated groups. The combined amounts of the thiol-containing and ethylenically-unsaturated compounds total at least 50 percent by weight of all polymerizable material in the polymerizable composition. The composition may be provide as a two-part composition. Polymerized reaction product of the composition and methods of making the composition are also disclosed.
