We claim: 1. A golf ball comprising at least one structural layer formed of a microporous composition comprising: at least one polymer component; a finely divided particulate filler comprising at least about 50 percent by weight of siliceous particles; and a network of interconnecting pores communicating substantially throughout the microporous composition, wherein the finely divided particulate filler is present in an amount of about 40 percent or greater by weight of the microporous composition. 2. The golf ball of claim 1, wherein the finely divided particulate filler comprises precipitated silica, a silica gel, fumed silica. 3. The golf ball of claim 1, wherein the interconnecting pores have a volume average diameter of about 0.02 microns to about 50 microns. 4. The golf ball of claim 1, wherein the finely divided particulate filler has an average particle size of about 100 nm or less. 5. The golf ball of claim 1, wherein the finely divided particulate filler has an average particle size of about 5 microns to about 40 microns. 6. The golf ball of claim 1, wherein the polymer component comprises ionomer resins, grafted and ungrafted metallocene-catalyzed polymers, single site catalyzed olefinic polymers, polyurethanes, polyureas, polyurethane-ionomers, polyurea-ionomers, polybutadiene, polyisoprene, ethylene propylene rubber, ethylene propylene diene monomer, styrene diene rubber block copolymers, polyamide, polyester, polyester-amide block copolymers, polyester-ether block copolymers, polyethylene-acrylic copolymers, polyethylene-methacrylic acid copolymers, polyethylene-acrylic terpolymer, polyethylene-methacrylic acid terpolymers, or mixtures thereof. 7. The golf ball of claim 1, wherein the golf ball comprises a core, a cover, and at least one layer formed of the microporous composition disposed between the core and the cover. 8. A golf ball comprising a core and a cover, wherein the cover is formed of a microporous composition comprising: a polymer component; and a finely divided silicate filler present in an amount of about 40 percent or greater by weight of the microporous composition, wherein the microporous composition comprises pores comprising about 35 percent or greater of the volume of the microporous composition, and wherein the pores have a volume average diameter of about 0.02 microns to about 50 microns. 9. The golf ball of claim 8, wherein the finely divided silicate filler has an average particle size of about 50 mm or less. 10. The golf ball of claim 8, wherein the pores comprise about 60 percent or greater of the volume of the microporous composition. 11. The golf ball of claim 8, wherein the pores have a volume average diameter of about 0.05 microns to about 30 microns. 12. The golf ball of claim 8, wherein the core comprises a rubber-based material. 13. The golf ball of claim 8, wherein the microporous composition further comprises a density-adjusting filler. 14. The golf ball of claim 8, wherein the microporous composition further comprises a processing plasticizer. 15. A golf ball comprising a structural layer formed of a microporous composition comprising: a polymer comprising polyurethane, polyurea, ionomer resin, or mixture thereof; a finely divided particulate filler comprising at least about 50 percent by weight of siliceous particles, wherein the finely divided particulate filler is present in an amount of about 40 percent or greater by weight of the microporous composition; and a network of interconnecting pores communicating substantially throughout the microporous composition. 16. The golf ball of claim 15, wherein the finely divided particulate filler comprises precipitated silica, silica gel, fumed silica, or a combination thereof. 17. The golf ball of claim 15, wherein the structural layer is a core layer. 18. The golf ball of claim 15, wherein the structural layer is a cover layer. 19. The golf ball of claim 18, further comprises a polybutadiene core and an ionomer resin inner cover layer, wherein the structural layer is disposed about the inner cover layer. 20. The golf ball of claim 15, wherein the network of interconnecting pores comprises about 35 percent to about 95 percent by volume of the microporous composition.
