Abstract:
An ionomer blend composition comprises a blend of a first ionomer and a second ionomer that is different from the first ionomer. The first ionomer is derived from a first precursor acid copolymer that has a melt flow rate of about 10 to about 4000 g/10 min and that comprises copolymerized units of an α-olefin and about 20 to about 30 wt % of copolymerized units of an α,β-ethylenically unsaturated carboxylic acid. Moreover, the first precursor acid can be neutralized to a level of about 40% to about 90% to form a sodium ionomer that has a MFR of about 0.7 to about 25 g/10 min and a freeze enthalpy that is less than about 3.0 j/g or that is not detectable, when determined by differential scanning calorimetry (DSC). A variety of articles may comprise or be produced from the ionomer blend composition, for example by injection molding.
Abstract:
A laminate comprises an ionomeric interlayer sheet which, in turn, comprises or is prepared from a sodium/zinc mixed ionomer that 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 α-olefin and an α,β-ethylenically unsaturated carboxylic acid, and it has a melt flow rate of about 70 to about 1000 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.

A safety laminate comprises an interlayer that comprises an ionomer that is the neutralized product of a precursor acid copolymer. The precursor acid copolymer comprises copolymerized units of a first α-olefin having 2 to 10 carbon atoms and about 20 to about 30 wt % of copolymerized units of a first α,β-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms; and has a melt flow rate of about 10 to about 4000 g/10 min. When neutralized to a level of about 40% to about 90% and when comprising counterions that consist essentially of sodium cations, the precursor acid copolymer produces a sodium ionomer that has a melt flow rate of about 0.7 to about 25 g/10 min and a freeze enthalpy that is not detectable or that is less than about 3.0 j/g. The ionomer composition may further comprise a second ionomer that has a melt flow rate of about 10 g/10 min or less.
