Reaction products useful as catalysts in the production of isocyanate-based plastics

摘要

A reaction product is formed from a tertiary amine and an acid mixture of (i) boric acid and (ii) a carboxylic acid. The reaction components are generally used in quantities such that the molar ratio of tertiary amine to acid mixture is from 1:0.1 to 1:10. The molar ratio of the boric acid to the carboxylic acid in the acid mixture is generally from 1:100 to 1:0.01. These reaction products are particularly useful as catalysts in the production of isocyanate addition products.
