| titleOfInvention | Method for preparing phosphorus-containing polyphenylene oxide resin with low molecular weight |
| abstract | Disclosed is a method for preparing a phosphorus-containing polyphenylene oxide resin with a low molecular weight, comprising the steps of: step 1: providing a phosphorus-containing phenolic compound and a raw polyphenylene oxide resin having a number-average molecular weight of more than 10000; step 2: dissolving the raw polyphenylene oxide resin into a solvent to make a solution of the raw polyphenylene oxide resin; step 3: adding the phosphorus-containing phenolic compound to into the solution of the raw polyphenylene oxide resin; step 4: introducing an initiator, and carrying out a re-dispersing reaction at a reaction temperature of above 60° C. under the effect of the initiator; and step 5: after the reaction is finished, the product obtained being phosphorus-containing polyphenylene oxide resin with a low molecular weight, the number-average molecular weight thereof being 1000-6000. n By dispersing the phosphorus-containing phenolic compound into the solution of polyphenylene oxide resin, and carrying out the re-dispersing reaction in the presence of the initiator to prepare the phosphorus-containing polyphenylene oxide resin with a low molecular weight, the obtained phosphorus-containing polyphenylene oxide resin with a low molecular weight is convenient to process, and suitable for use as the matrix resin of composite materials for high-frequency circuit boards or as an additive component for other polymeric materials. |
