Claims
- 1. An article comprising a substrate having injection molded into its surface a melt-reacted blend, said blend comprising a major amount of an ethylene/olefinically-unsaturated carboxylic acid copolymer having uniformly mixed therein a minor amount of a masterbatch comprising a metal oxide/ethylene polymer blend, wherein said ethylene polymer comprises LDPE, HDPE, or LLDPE,
- whereby the melt-reacted blend is caused to be substantially homogeneous and compositionally uniform by virtue of having had the metal oxide in the masterbatch uniformly mixed with the ethylene/olefinically-unsaturated carboxylic acid copolymer.
- 2. The article of claim 1. wherein the carboxylic acid comprises acrylic acid or methacrylic acid.
- 3. The article of claim 1. wherein the carboxylic acid comprises acrylic acid.
- 4. The article of claim 1. wherein the carboxylic acid comprises methacrylic acid.
- 5. The article of claim 1. wherein the ethylene polymer comprises LDPE.
- 6. The article of claim 1. wherein the ethylene polymer comprises HDPE.
- 7. The article of claim 1. wherein the ethylene polymer comprises LLDPE.
- 8. The article of claim 1, wherein the metal oxide is at least one of CaO, MgO, BaO, and ZnO.
- 9. The article of claim 1. wherein the metal oxide is MgO.
- 10. The article of claim 1 wherein the article is a golf ball.
- 11. An article comprising a substrate having injection molded onto its surface a melt-reacted blend, said blend comprises a major amount of an ethylene/carboxylic acid copolymer and a minor amount of a masterbatch comprising a metal oxide/ethylene polymer blend, wherein said ethylene polymer comprises LDPE, HDPE, or LLDPE.
- 12. The article of claim 11 wherein the carboxylic acid comprises acrylic acid or methacrylic acid.
- 13. The article of claim 11 wherein the carboxylic acid comprises acrylic acid.
- 14. The article of claim 11 wherein the carboxylic acid comprises methacrylic acid.
- 15. The article of claim 11 wherein the ethylene polymer comprises LDPE.
- 16. The article of claim 11 wherein the ethylene polymer comprises HDPE.
- 17. The article of claim 11 wherein the ethylene polymer comprises LLDPE.
- 18. The article of claim 11 wherein the metal oxide is at least one of CaO, MgO, BaO, and ZnO.
- 19. The article of claim 11 wherein the metal oxide is MgO.
- 20. The article of claim 11 wherein the article is a golf ball.
