HIGH-CLARITY BLENDED IONOMER COMPOSITIONS AND ARTICLES COMPRISING THE SAME |
摘要 |
<p>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,&bgr;-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.</p> |
