Abstract:

Polymer forming reactions have been previously known comprising five and six member oxazoline ring oxazolidines and reaction products containing the basic structure with polyfunctional aromatic and aliphatic isocyanates and moisture. Five types of oxazolidines have been previously illustrated. Use of these polymeric products have been found to be limited as the class of oxazolidines described in the prior art result in objectionable dark colored products. This invention relates to an advance thereover in providing light colored end products by use of a novel and specific dioxazabicyclo octanes, a substituted specialized class of oxazolidine ring compounds.
