SILYL-PROTECTED NITROGEN-CONTAINING CYCLIC COMPOUNDS AND MAKING METHOD

摘要

Silyl-protected nitrogen-containing cyclic compounds having formula (1) are provided wherein R1, R2 and R3 each are a monovalent hydrocarbon group, R4 and R5 each are a divalent hydrocarbon group, R6, R7 and R8 each are H or a monovalent hydrocarbon group. A is —C(O)OR9 or —C≡N, R9 is a monovalent hydrocarbon group, and a is 0 or 1. The compounds are added to polyurethane, polyester or polycarbonate resins to form one part type curable compositions for imparting stiffness, mechanical strength and transparency thereto.;
