Preliminary kinetic data has been obtained on a model spiro ortho ester. Spiro ortho esters are a class of monomers which have near zero shrinkage or even slight expansion when they polymerize. The concept of having expanding monomer systems is an important consideration in improving potting materials, adhesives, structural resins, and casting resins for industrial and military applications. The kinetic data to date indicates that competing side reactions occur during the polymerization of spiro ortho esters. The influence of these side reactions must be minimized by changes in temperature or catalyst in order to realize fully the potential of this class of materials. Author
