  The molecular weight of crystalline propylene polymer can be lowered, giving an environmentally stable plastic composition having narrow molecular weight distribution by visbreaking a propylene polymer using an activated portion (e.g. 0,5 to 50%) of the propylene polymer as a prodegradant. The prodegradant is formed by activating a portion of the propylene polymer by exposure to ionizing radiation. Visbreaking takes place at 200 to 300°C by shear mixing in an extruder.

  使用丙烯聚合物的活化部分（如 0.5%至 50%）作为原降解剂对丙烯聚合物进行减粘后，可降低结晶丙烯聚合物的分子量，从而得到分子量分布较窄的环境稳定塑料组合物。 原降解剂是通过电离辐射对部分丙烯聚合物进行活化而形成的。 减粘在 200 至 300°C 温度下通过挤压机中的剪切混合进行。

  A golf ball includes a single core having an outer surface and a geometric center. The core is formed from a substantially homogenous rubber composition. An inner cover layer is disposed about the core, the inner cover including a high-acid ionomer and having a material hardness of about 66 to 75 Shore D. The high-acid ionomer has an acid content of about 16% or greater. An outer cover layer is disposed about the inner cover layer, the outer cover including a polyurethane and having a material hardness of about 38 Shore D to about 56 Shore D. The core surface hardness is from 0 Shore C to 15 Shore C lower than the geometric center hardness to define a hardness gradient.

  Golf ball comprising a core having a hardness gradient 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.
