HIGH CLARITY LAMINATED ARTICLES COMPRISING AN IONOMER INTERLAYER |
摘要 |
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,&bgr;-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.
