    Abstract: Golf ball incorporating thermoplastic blend of (i) ionomer(s); (ii) different thermoplastic polymer(s) selected from thermoplastic polyurethane(s), thermoplastic urea(s), and/or thermoplastic urea-urethane hybrid(s); and (iii) polyester elastomer(s) and/or polyamide elastomer(s) (“PEPA”). Ionomer is present in amount of about 45 wt % or greater and PEPA present in amount of from about 2 wt % to about 35 wt %. Thermoplastic polymer(s) may be present in amount of from about 8 wt % to about 50 wt %; or from about 25 wt % to about 45 wt %; or from about 35 wt % to about 50 wt %. Ionomer amount may be greater than amount of thermoplastic polymer. Thermoplastic polymer may be a polyurethane present in amount of greater than 20 wt % and to about 40 wt %; while the PEPA is present in amount of from about 5 wt % to about 30 wt %. PEPA is sometimes present in an amount of from about 15 wt % to about 35 wt %.

    Abstract: Golf ball comprising a positive hardness gradient core and an outer cover layer having a microhardness gradient and being formed from a thermoset polyurethane material throughout, and having: i) a treated region that is contacted with a thermoset polyurethane microhardness-increasing solution consisting of an isocyanate portion and at least one non-aqueous solvent; and ii) an untreated region that is not contacted with the thermoset polyurethane microhardness-increasing solution. The treated region comprises the isocyanate portion, whereas the untreated region does not comprise the isocyanate portion. Treated region has a microhardness M1 that is greater than microhardness M2 of untreated region to define the outer cover layer positive microhardness gradient ΔM=M1−M2. The treated region may have a depth Dtr that extends inward from the cover outer surface and in some embodiments is less than a thickness of the untreated region. Treated region may alternatively extend from the inner surface toward outer surface.
