HYDROXY-TERMINATED POLYBUTADIENE (HTPB) BASED POLYURETHANE FORMULATIONS CATALYZED BY AN IMIDAZOLE DERIVATIVE

摘要

the invention relates to formulations based on polyurethanehydroxylated polybutadiene catalyzed by imidazole derivative, n - substituted.this is an improvement on the conventional catalysts, catalystbased on the mercury salt. in fact, there is no environmental problem andis a specific viscosity for a timelying in a.
