Dispersion of filler(s) in polymeric compositions are improved by the use of a polymer-filler coupling compound, Q-A-B, wherein Q comprises a dipolar nitrogen-containing moiety that can form a 1,3 dipolar addition to an unsaturated carbon-carbon bond; B is an oxazoline, thiazoline, alkoxysilane or allyltin moiety, and A is a linking atom or group that forms a bridge between Q and B.
在聚合物组合物中,通过使用聚合物填料偶联化合物Q-A-B,填料的分散性得到改善,其中Q包括一个偶极氮含量的基团,可以与不饱和碳-碳键形成1,3-偶极加成;B是氧唑烯,
噻唑烯,烷氧基
硅烷或烯基
锡基团,A是一个连接原子或基团,形成Q和B之间的桥梁。
