摘要： The present invention is directed to golf balls comprising a cover and a core, wherein the cover is formed from a blend which comprises a base ionomer resin and a color concentrate comprising a coloring agent and a carrier ionomer resin. The relationship between the acid content of the base ionomer resin (X), wherein (X) is at least about 15% by weight and the acid content of the carrier ionomer resin (Y) is X-Y.ltoreq.4. Golf balls made with covers having base ionomer resins and carrier ionomer resins meeting the above relationship exhibit superior durability characteristics, including a significant reduction flow front failures and delamination as compared to golf ball covers which do not meet the above relationship.

摘要： Blend compositions are provided comprising first polyvinyl chloride and a second polyvinyl chloride wherein the inherent viscosity (I.V.) of the second polyvinyl chloride, measured in accordance with ASTM1243 is at least about 0.2 units higher than the I.V. of the first polyvinyl chloride. Preferably the I.V. of the second polyvinyl chloride is from 0.2 to 1.0 units higher than the I.V. of said first polyvinyl chloride, with the most preferred difference in I.V. (.DELTA.I.V.) being 0.35 to 0.65 units so as to yield a balance of property improvements including impact resistance, heat distortion temperature, melt flow and melt viscosity. The compositions also can further comprise melt flow enhancers and/or Tg enhancing agents. The blends of the present invention are processible by a variety of techniques including injection molding, extrusion, calendering, thermoforming, compression molding and the like to form useful articles such as molded sheets, trays, shrouds as for fans, appliance parts and covers, electrical outlets, business machine housings, telecommunication equipment, automotive components, and numerous others.
