  • Compound having bis phenylene group substituted with alkylamide, composition for controlling polyphenylene polymer flowability and method of polyphenylene polymer flowability control using the same
    Patent number: 10927237
    Abstract: The present invention relates to a compound having a bis phenylene group substituted with alkylamide, a composition comprising the same for the control of polyphenylene polymer flowability and a method for controlling polyphenylene polymer flowability using the same. The said compound can improve the flowability of polyphenylene polymer so that it can be used for processing polyphenylene polymer to improve the flowability, thereby providing economic benefits by diversifying PPS parts and improving workability. In addition, the said compound can control and improve the flowability by regulating the length of phenyl-conjugated alkyl, so that it can be effectively used as a flowability regulator of polyphenylene polymer particularly polyphenylene sulfide.
