Abstract: The invention includes a cross-linking composition comprising a cross-linking compound and a cross-linking reaction additive selected from an organic acid and/or an acetate compound, wherein the cross-linking compound has the structure according to formula (IV): wherein the cross-linking reaction additive is capable of reacting with the cross-linking compound to form a reactive oligomer intermediate, which is capable of cross-linking an organic polymer. Also included is an organic polymer composition for use in forming a cross-linked organic polymer, comprising a cross-linking compound of Formula (IV), a cross-linking reaction additive and at least one organic polymer. In one embodiment, the at least one organic polymer has at least one halogen-containing reactive group and is dehalogenated by reacting with an alkali metal compound.

Abstract: Methods are disclosed to prepare elastomeric materials by providing aromatic polymer(s) which is/are non-elastomeric at room temperature; cross-linking the aromatic polymer using a cross-linking compound to form a cross-linked aromatic polymer which is substantially cured; and heating the cross-linked aromatic polymer to a temperature at or above a glass transition temperature of the cross-linked aromatic polymer. Materials formed thereby and end products are also described which may be formed using the aromatic polymer cross-linking techniques to develop strong elastomeric materials for high temperature and/or harsh condition end applications.
