Method for preparing reactive triazine-capped aromatic polymers, and intermediates for use therein |
摘要 |
Hydroxy group-containing polymers, particularly polyphenylene ethers, are capped by reaction with a chlorotriazine in the presence of a substantially inert organic liquid such as toluene, water, a phase transfer catalyst and a tertiary amine from a specific class, preferably a trialkylamine such as triethylamine or dimethyl-n-butylamine. The reaction proceeds rapidly and in good yield.
