Abstract
Abstract New products and methods for their preparation; principally, 3-(glycidyl)-1,3-oxazolidines and derivatives thereof obtained via the reaction of a 3-(glycidyl)-1,3-oxazolidine with an amine, alcohol, sulfonate, mercaptan, azide or cyanide. Also covered are oxazolidines containing a carboxy function which are obtained by treating a 3-(glycidyl)-1,3-oxazolidine with a mono-or poly-carboxylic acid. The products are useful in improving the adhesiveness of polymers and in promoting the room temperature cure of isocyanate and anhydride polymers to afford new plastic, adhesive and coating materials.
