摘要： Polyurethane formulations based on hydroxylated polybutadiene are catalyzed by an N-substituted imidazole derivative. This type of catalysis advantageously replaces the conventional catalysts based on mercury salt. The catalysis does not pose an environmental problem and allows a particular increase in viscosity, permitting an extended pot life and rapid setting.
