Abstract

This invention relates to the process and the product by process of the polymers formed by the polymerization of polycyclic ring-opening monomers. More particularly, this invention relates to the novel process and product by process of polymers that are produced with near zero shrinkage or expansion during polymerization and are immediately useful for production of strain-free composites, high strength adhesives, precision castings, binders for propellants and as additives to other monomer mixtures to produce a mixture that controls the amount of shrinkage or expansion upon polymerization.
