A composition that includes functionalized polymers and particulate filler is provided. The composition includes at least three components: (1) a polymer that includes a first type of functionality such as a functional group including a primary or secondary amine functionality, (2) a polymer that includes a second type of functionality such as an alkoxysilane or other silica interacting functionality, and (3) at least two types of particulate filler. One of the functionalized polymers can be made in the presence of the other.
