Patent ID: 8795834

Claim:
A synthetic turf infill cooling granule comprising: a core particle having an outer surface; and a superabsorbent polymer composition comprising: (a) one or more water-soluble polymers; and (b) one or more cross-linking agents; wherein the one or more water-soluble polymers comprise polymerizable unsaturated monomers with one or more acid functional groups; wherein from 5 to 30% of the acid groups on the one or more water-soluble polymers are crosslinked by the one or more crosslinking agents to form a superabsorbent polymer composition that is water-swellable and substantially water insoluble but capable of absorbing at least about 5 times its weight in water; wherein the superabsorbent polymer composition forms a coating over the outer surface of the core particle and comprises about 0.2% to about 10% by weight of the core particle; wherein the size of the coated particle has a median size that is within a range of about 5 to about 60 mesh; and wherein the core particle comprises a granular material selected from the group consisting of resilient particles, inelastic particles or combinations thereof.
