Golf ball having CoR of at least 0.700 and Atti compression of at least about 50 and comprising layer comprising a mixture of ionomer composition and a plurality of particulates, at least some being surface-treated with alkoxylated siloxanes and/or polyether-modified siloxanes, and selected from titanium dioxide particles, barium sulfate particles, zinc sulfide particles, and/or zinc oxide particulates. At least some particulates may be contacted with compound having the formula: n n n n n n n n n n Compound (I) may be included in amount of 0.01 to 2% by weight based on total weight of portion of plurality being contacted. The plurality may be included in mixture in amount such that the layer has specific gravity of from 0.5 to about 5.0, tensile strength of from about 300 psi to about 50,000 psi, and elongation at break of from about 20% to about 1000%, each being greater than that of the ionomer composition portion of the mixture. |
