WebJan 1, 1980 · Both diallyl o-phthalate and diallyl m-phthalate may be converted to "prepolymers," which are soluble in a variety of solvents. These two prepolymers are commercially available. When dissolved in their respective monomers and heated in the presence of typical initiators, such solutions are converted to cross-linked resins.
