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 solar cell module comprising a solar cell layer and an ionomer sheet comprising a sodium/zinc mixed ionomer that is the neutralization product of a precursor acid copolymer; wherein the precursor acid copolymer comprises copolymerized units of an α-olefin having 2 to 10 carbon atoms and about 20 to about 30 wt % of copolymerized units of an α,β-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms based on the total weight of the precursor acid copolymer; wherein the precursor acid copolymer has a melt flow rate of about 70 to about 1000 g/10 min, as determined in accordance with ASTM D1238 at 190° C. and 2.16 kg; and wherein when about 40% to about 90% of the total content of the carboxylic acid groups present in the precursor acid copolymer are neutralized to carboxylate groups to comprise carboxylate groups and counterions that consist essentially of sodium ions, the resulting sodium ionomer has a freeze enthalpy that is not detectable or that is less than about 3.0 j/g, when determined by differential scanning calorimetry in accordance with ASTM D3418.

Abstract:
Provided is a high performance anti-spall laminate article comprising a bi-layer polymeric composite. The bi-layer composite includes a polymeric sheet and a poly(ethylene terephthalate) (PET) film laminated to each other. The PET film has a tensile modulus of about 600,000 psi or higher in both the machine direction (MD) and the transverse direction (TD), a shock brittleness index of about 55 Joules or higher in the machine direction and about 25 joules or higher in the transverse direction, and a percent elongation at break (EOB) of about 110-160 in the machine direction and about 60-110 in the transverse direction.
Abstract:
The present invention is a method for reducing the permeability of gases through polyester containers and films by incorporating into the polymer from which the container or film is formed an effective amount of exfoliated sepiolite-type clay.
