In various embodiments the present invention comprises 2,4,6-trisubstituted-1,3,5-triazine capping agents comprising one, two, or three leaving groups as substituents with any remaining substituents being essentially inert to reaction with a nucleophilic group on a polymer or monomer, or reactive with a nucleophilic group on a polymer or monomer at a slower rate than any leaving group. The invention also comprises polymers or monomers with nucleophilic groups capped with a triazine moiety. Still other embodiments of the invention comprise processes for capping nucleophilic groups in a polymer or monomer which comprises combining and reacting the polymer or monomer with a triazine-comprising capping agent.
在各种实施例中,本发明包括具有一个、两个或三个离去基团作为取代基的2,4,6-三取代-1,3,5-三嗪封顶剂,其余取代基本质上对与聚合物或单体上的亲核基团反应是惰性的,或者与聚合物或单体上的亲核基团反应的速率比任何离去基团慢。本发明还包括具有三嗪基团封顶的含有亲核基团的聚合物或单体。本发明的其他实施例还包括封顶聚合物或单体中的亲核基团的过程,其中包括将聚合物或单体与含三嗪的封顶剂结合并反应。
