| 20090242030 | HIGH PERFORMANCE ANTI-SPALL LAMINATE ARTICLE - 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. | 10-01-2009 |
| 20090324935 | TRANSPARENT LIGHT-WEIGHT SAFETY GLAZINGS - Provided is a transparent and light-weight ballistic resistant safety glazing comprising an ionomer sheet. The ionomer sheet comprises an ionomer derived from a parent acid copolymer that comprises copolymerized units of an α-olefin having 2 to 10 carbon atoms and, based on the total weight of the acid copolymer, about 20 to about 30 wt % of copolymerized units of an α,β-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms. The ionomer is neutralized to a level of about 5% to about 90%, based on the total carboxylic acid content of the acid copolymer, and further comprises at least one cation. Further provided are articles comprising the light-weight ballistic resistant safety glazing. | 12-31-2009 |
| 20100062236 | TRANSPARENT LIGHT-WEIGHT SAFETY GLAZINGS - Provided is a transparent and light-weight ballistic resistant safety glazing comprising an ionomer sheet. The ionomer sheet comprises an ionomer derived from a parent acid copolymer that comprises copolymerized units of an α-olefin having 2 to 10 carbon atoms and, based on the total weight of the acid copolymer, about 20 to about 30 wt % of copolymerized units of an α,β-ethylenically unsaturated carboxylic acid having 3 to 8 carbon atoms. The ionomer is neutralized to a level of about 5% to about 90%, based on the total carboxylic acid content of the acid copolymer, and further comprises at least one cation. Further provided are articles comprising the light-weight ballistic resistant safety glazing. | 03-11-2010 |
| 20100112356 | HIGH CLARITY LAMINATED ARTICLES COMPRISING AN IONOMER INTERLAYER - 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. | 05-06-2010 |
| 20100154867 | MECHANICALLY RELIABLE SOLAR CELL MODULES - A thin film solar cell module comprising thin film solar cells deposited on a first float glass sheet, an ionomer encapsulant sheet and a float glass protective sheet. | 06-24-2010 |
| 20100167061 | LAMINATES COMPRISING IONOMER INTERLAYERS WITH LOW HAZE AND HIGH MOISTURE RESISTANCE - 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. | 07-01-2010 |
