Abstract
Compositions of arylene oligomers and certain curing agents are useful to provide arylene polymer coatings having improved mechanical properties when cured in an oxygen-containing atmosphere. Methods of curing such compositions are also provided.
Claims13
A composition comprising one or more curable arylene oligomers comprising as polymerized units one or more first monomers having two cyclopentadienone moieties and one or more second monomers having two or more alkyne moieties;
- one or more curing agents of the formula
- wherein Ar4, Ar5 and Ar6 are independently aromatic moieties having from 1 to 3 aromatic rings, each of which may be unsubstituted or substituted;
- wherein in at least one of Ar4, Ar5 and Ar6 is substituted with hydroxyl;
- and one or more organic solvents.
A method of curing an arylene oligomer comprising:
- disposing a composition comprising one or more curable arylene oligomers comprising as polymerized units one or more first monomers having two cyclopentadienone moieties and one or more second monomers having two or more alkyne moieties;
- one or more curing agents of the formula
- wherein Ar4, Ar5 and Ar6 are independently aromatic moieties having from 1 to 3 aromatic rings, each of which may be unsubstituted or substituted;
- wherein in at least one of Ar4, Ar5 and Ar6 is substituted with hydroxyl;
- and one or more organic solvents on a substrate surface;
- at least partially removing the one or more organic solvents;
- and curing the one or more arylene oligomers in air to form a cured arylene coating on the substrate.
A method of forming a coated inorganic film comprising:
- providing an inorganic film;
- coating a layer of a composition comprising one or more curable arylene oligomers comprising as polymerized units one or more first monomers having two cyclopentadienone moieties and one or more second monomers having two or more alkyne moieties;
- one or more curing agents of the formula
- wherein Ar4, Ar5 and Ar6 are independently aromatic moieties having from 1 to 3 aromatic rings, each of which may be unsubstituted or substituted;
- wherein in at least one of Ar4, Ar5 and Ar6 is substituted with hydroxyl;
- and one or more organic solvents on a surface of the inorganic film;
- removing the one or more organic solvents from the coating layer;
- curing the coating layer in air to form a coated inorganic film.
