摘要：
Curable cyanoacrylate compositions are reported that comprise cyanoacrylate and a thermoplastic polyurethane (TPU) components. Such compositions are toughened cyanoacrylate compositions exhibiting long term viscosity stability when stored for prolonged periods at room temperature (25°C). TPU components are reported having structural units in which at least one of the structural units has the formula: -O-R 1 -O-Ar-O-R 2 -O-, wherein Ar is a C 6 -C 20 aromatic group with at least one aromatic ring; R 1 is a C 2 -C 10 alkyl group; and R 2 is a C 2 -C 10 alkyl group. The thermoplastic polyurethane (TPU) component may be present in the curable cyanoacrylate composition from about 1 wt% to about 40 wt%, for example from about 2 wt% to about 30 wt%, such from about 3 wt% to about 20 wt%, suitably from about 5 wt% to about 10 wt%, based on the total weight of the composition.
