PURPOSE: To provide a reactive terminal substituent capable of forming a large number of polymer and copolymer-containing compds. being originally incompatible with polyphenylene ether. n CONSTITUTION: Substd. alkoxy- or alkylthiotriazine capped polyphenylene ethers have terminal groups represented by formula I. In the formula I, groups Q 1 are respectively independently halogen, primary or secondary lower alkyl or phenyl, groups Q 2 are respectively independently hydrogen, halogen, primary or secondary alkyl, X 1 is alkyl, cycloalkyl or aromatic, X 2 can be substituted by a nuleophilic aliphatic substitutent, groups Z are respectively independently an oxygen atom or a sulfur atom, groups R 1 are respectively independently hydrogen or 1-4C primary or secondary alkyl, R 2 is a non-substd. 1-3C alkylene group, groups R 3 are respectively independently R 1 or X 2 , (m) is 0 or 1 and (n) is 1-3. n COPYRIGHT: (C)1992,JPO |
