Claim 7:
8. A second composite material comprising a reaction product of a second reactive filler and a functionalized polymer,
wherein the second reactive filler comprises a second reactive substrate composition comprising a second reaction product of a base composition and a secondary coupling agent having at least two functional groups, wherein the base composition comprises a first reactive substrate composition comprising a reaction product of:
a) an inorganic substrate
i) having a surface comprising a concentration of hydroxyl groups, a concentration of μ-bonded oxygen groups, or a combination thereof; and
ii) comprising a water content of less than or equal to 5 ppm; and

b) a primary coupling agent, comprising a Group 13 element-based coupling agent represented by Formula I, an alumoxane compound, or a combination thereof,
wherein:
Formula I is:, M represents a Group 13 element;
R1, R2, and R3 each independently represent hydrogen, a halogen, or a linear or branched hydrocarbyl having up to 20 carbons and optionally comprising one or more cyclic and/or aromatic structures and/or one or more hetero atoms, and comprise no olefinic unsaturation;
the primary coupling agent reacts with at least a portion of the hydroxyl groups and/or μ-bonded oxygen groups to covalently or ionically bond the reacted primary coupling agent to the inorganic substrate; and the first reactive substrate composition has a surface comprising a concentration of reacted primary coupling agent; at least one functional group of the second coupling agent reacts to form a covalent or ionic bond with the base composition; and the second reactive substrate composition has a surface comprising at least one other functional group of the reacted secondary coupling agent; and
wherein the functionalized polymer:
i) comprises one or more functional groups capable of forming a covalent or ionic bond with the at least one of the functional group of the reacted secondary coupling agent on the surface of the second reactive substrate composition; and
ii) has a molecular weight ranging from oligomers of two mer units, wherein the two mer units is the same or different, to a weight average molecular of 1M g/mol.
