摘要:
A resist composition comprising a base polymer and a phosphazene salt compound offers a high dissolution contrast, minimal LWR, and dimensional stability on PPD.
摘要:
A phosphorous flame retardant primarily includes hexachlorotriphosphazene (HCP) having poly(oxyalkylene)amine substitutes. The poly(oxyalkylene)amine includes at least two end groups. The phosphorous flame retardant can further include layered silicate clay. The layered silicate clay can be intercalated and modified with the poly(oxyalkylene)amine substitutes of HCP to effectively promote thermal stability. The flame retardant, phosphazene-poly(oxyalkylene)amine adducts, can be applied to a polymer. By the cross-linking between them, the flame-retarding property of the polymer can be improved. Also provided is a method for producing the flame retardant of phosphazene-poly(oxyalkylene)amine adducts and application thereof to a polymer.
摘要:
Disclosed is a phosphazene compound and a photosensitive resin composition. The phosphazene compound is obtained by reacting a phenoxyphosphazene compound (A-1) having a phenolic hydroxyl group and/or a cross-linked phenoxyphosphazene compound (A-2) obtained by cross-linking the phenoxyphosphazene compound (A-1) with an epoxy compound (B) having an unsaturated double bond and/or an isocyanate compound (C), wherein the phosphazene compound has an unsaturated double bond in its molecule. The photosensitive resin composition includes at least: a soluble polyimide resin (G-1) having a carboxyl group and/or a hydroxyl group and is soluble in an organic solvent, as the polyimide resins (G); and a phenoxyphosphazene compound (H-1) having a phenolic hydroxyl group and/or a cross-linked phenoxyphosphazene compound (H-2), which is obtained by cross-linking the phenoxyphosphazene compound (H-1) and has at least one phenolic hydroxyl group, as the phosphazene compound (H), and the photosensitive resin composition further includes a (meth)acrylic compound (L).
