| titleOfInvention | Polyphenylene ether and method for producing the same |
| abstract | The present invention provides polyphenylene ether, which is a low-molecular-weight polyphenylene ether with improved workability and predicted physical properties during heat processing, and a method for producing the same. The weight-average molecular weight (Mw) of the polyphenylene ether of the present invention is 2500-6000, the ratio (Mw/Mn) of the weight-average molecular weight to the number-average molecular weight (Mn) is 1.0-2.0, and every 100 phenylenes constituting the resin In the ether unit, the total number of terminal groups represented by the following general formula (1) and general formula (2) is 0.8 or less. (In formula (1), R 1 to R 3 are each independently selected from the group consisting of a hydrogen atom, an alkyl group, a substituted alkyl group, a halogen group, an aryl group and a substituted aryl group, R 4 and R 5 are hydrogen, and R 6 is selected from the group consisting of alkyl, substituted alkyl, alkenyl, substituted alkenyl, aryl and substituted aryl. In formula (2), R 1 to R 5 have the same definitions as in general formula (1), R 7 , R 8 are each independently selected from the group consisting of a hydrogen atom, an alkyl group, a substituted alkyl group, an aryl group, and a substituted aryl group, but they are not simultaneously hydrogen.) |
