摘要

Branched polyfunctional carbodiimides of formula I CHEM wherein: M and Q are independently the residue of a compound adapted to function as a site for branching; R1, R2, R4, R5, R6, and R7 are independently divalent organic radicals; R3 and R8 are independently monovalent organic radicals; a is 3 to 6; b, e, f and g are 0 to 4; and e, d, and h are 0 or 1; are disclosed which are monodisperse, i.e., have exact functionality and molecular weight distribution. Compsoitons based on these polyfunctional carbodiimides have low viscosity relative to their molecular weight and are particularly useful as cross-linkers for carboxyl-containing resins.
