An adhesive composition including as principal components:(a) about 10-90% by weight of at least one free radical-polymerizable monomer,(b) about 0-20% by weight of an adhesion promoter,(c) about 10-80% by weight of a primary low molecular weight toughener (or toughening agent) with a weight average molecular weight (Mw) less than about 18,000 or a number average molecular number (Mn) less than about 10,000 and;(d) about 1-15% by weight of an auxiliary high molecular weight toughener (or toughening agent) with a Mw greater than about 18,000 or a Mn greater than about 10,000based on the total weight of components (a)-(d). |
