摘要:Disclosed in the present invention are a polyimide precursor and a synthetic method therefor, and a photosensitive resin composition comprising the polyimide precursor. The synthesis method comprises: in a solvent, reacting a dianhydride, an alcohol having a free radical polymerizable unsaturated double bond, and a side-chain modifier under the catalysis of a basic catalyst; adding a dehydration condensation agent thereto, and stirring the mixture; adding a diamine thereto for reaction, finally adding an end-capping agent to quench the reaction, and filtering the mixture; and adding the filtrate to a poor solvent within 0-2 h, precipitating a solid polyimide precursor resin, and refrigerating same, wherein the side-chain modifier is selected from any one or more of an alcohol side-chain modifier, an ether alcohol side-chain modifier and an amine side-chain modifier; and the end-capping agent is selected from any one or more of an alcohol end-capping agent, an ether alcohol end-capping agent and an amine end-capping agent. On the basis of not changing the main structure of the polyimide precursor, the present invention improves the dissolvability of the functional resin, controls the dissolution rate thereof, and ensures the performance of the final polyimide film after the functional resin has been heated and cured.

摘要:An aromatic ether oligomer or polyaromatic ether comprising the formula:n n O—Ar n ;n nwherein Ar is an independently selected divalent aromatic radical; formed by reacting a dihydroxyaromatic with a dihaloaromatic; and wherein the reaction is performed in the presence of a copper compound and cesium carbonate. The polyaromatic ether is formed when neither the dihydroxyaromatic nor the dihaloaromatic is present in an excess amount. The aromatic ether oligomer is formed by using an excess of either dihydroxyaromatic or dihaloaromatic. A phthalonitrile monomer comprising the formula:n n nformed by reacting a 3- or 4-nitrophthalonitrile with a hydroxy-terminated aromatic ether oligomer. A thermoset formed by curing the phthalonitrile monomer. Processes for forming all the above.

摘要:A crosslinkable thermoplastic resin composition may include a polymer formed from the reaction between a bis-benzoxazine monomer and a bifunctional comonomer having phenol, amine, and/or thiol functional groups, wherein the polymer contains at least one crosslinkable group. A method of forming a crosslinkable thermoplastic resin composition may include reacting a bis-benzoxazine monomer and a bifunctional comonomer to form a polymer containing at least one crosslinkable group. A method of forming a cured thermoplastic resin may include curing the crosslinkable thermoplastic resin composition by applying an external stimulus.
