| titleOfInvention | A kind of polyethers amine type benzoxazine prepolymer and preparation method thereof |
| abstract | The present invention relates to a kind of polyethers amine type benzoxazine prepolymer and preparation method thereof, aldehyde compound, bisphenol-A and polyether amine compound are added into reaction vessel, amido mol ratio of the aldehyde radical with the phenolic hydroxyl group in bisphenol-A, in polyether amine compound is 2~2.4 wherein in aldehyde compound：1~1.2：1~1.2, organic solvent dissolving is added, reacts 6~10h in 80~110 DEG C, reaction solution is poured into methanol solution and precipitated by reaction after terminating, milky suspension is obtained, removing supernatant liquor after standing obtains white precipitate, is ground after white precipitate is dried and obtains polyethers amine type benzoxazine prepolymer.The performed polymer, which finally solidifies obtained polyethers amine type benzoxazine colophony, has excellent heat resistance, mechanical property and dielectric properties, can be widely used in the composites such as copper-clad plate, laminate. |
