Patent number: 8334033Abstract: A sodium/zinc mixed ionomer comprises carboxylate groups and a combination of counterions that consists essentially of sodium cations and zinc cations. The sodium/zinc mixed ionomer is the neutralization product of a precursor acid copolymer. The precursor acid copolymer comprises copolymerized units of an ?-olefin and an ?,?-ethylenically unsaturated carboxylic acid, and it has a melt flow rate of about 10 to about 4000 g/10 min. In addition, the precursor acid copolymer, when neutralized to a level of about 40% to about 90%, and when comprising counterions that consist essentially of sodium ions, produces a sodium ionomer that has a freeze enthalpy that is not detectable or that is less than about 3.0 j/g, when determined by differential scanning calorimetry. Further provided are articles comprising or prepared from the sodium/zinc mixed ionomer.Type: GrantFiled: November 2, 2009Date of Patent: December 18, 2012Assignee: E I du Pont de Nemours and CompanyInventors: Karlheinz Hausmann, Richard Allen Hayes, Steven C.

Patent number: 8088026Abstract: A phase transition golf ball comprises a phase transition material. The phase transition material may optionally include a microwave susceptor or an induction susceptor. The phase transition material preferably comprises an ethylene acid copolymer, or an ionomer of an ethylene acid copolymer. The performance of the phase transition golf ball, for example its hardness or compression, is adjusted by inducing a complete or partial phase transition in the phase transition material. The extent of the adjustment in performance is correlated with the extent of the phase transition. Preferably, the phase transition is reversible and repeatable and takes place at temperatures that might be achieved through the use of common household appliances. Also preferably, the phase transition material returns to its original state over an extended period, for example hours or days.Type: GrantFiled: October 3, 2007Date of Patent: January 3, 2012Assignee: E.
