This specification generally relates to aqueous compositions for preparing UV stable fire-resistant interlayers. It also relates to UV stable fire-resistant glazing laminates comprising such interlayers, the use of such glazing laminates in construction, and constructions comprising such glazings. An example aqueous composition comprises a mixed alkali metal silicate of general formula SiO.sub.2.Math.M.sub.2O, where M is K or Na, and other organic and inorganic additives. Glazings with interlayers made with such aqueous compositions are simple to prepare and demonstrate good UV stability and fire-protection properties.

Provided herein are glass laminates, preferably safety glass laminates, that comprise a polymeric interlayer sheet formed of an acid copolymer composition. The acid copolymer composition comprises an ethylene acid copolymer which, in turn, comprises copolymerized units of ethylene, about 5 to about 90 wt % of copolymerized units of a first ,-unsaturated carboxylic acid having 3 to 10 carbon atoms; and optionally about 2 to about 40 wt % of copolymerized units of a derivative of a second ,-unsaturated carboxylic acid having 3 to 10 carbon atoms. Optionally, a portion of the carboxylic acid groups of the copolymerized units of the ethylene acid copolymer are neutralized to form carboxylate salts. The acid copolymer composition also includes a hydroxyl-containing crosslinking agent and may also include an adjuvant. The glass laminates have superior resistance to creeping due to the properties of the acid copolymer composition, which may optionally be cross-linked.

The invention is directed to a polymer sheet and its use as part of a solar panel and glass element. The sheet comprises multiple coextruded polymer layers, wherein at least two or more layers of the polymer sheet comprise a luminescence downshifting compound for at least partially absorbing radiation having a certain wavelength and re-emitting radiation at a longer wavelength than the wavelength of the absorbed radiation, and wherein a luminescence downshifting compound in a first polymer layer can absorb more radiation at a lower wavelength than the luminescence downshifting compound present in a next layer.

A photo-crosslinkable ethylene-based resin composition of the present invention includes an ethylene-based copolymer having a Shore A hardness measured in accordance with ASTM D2240 of equal to or more than 55 and equal to or less than 95, a photo-crosslinking initiator, and a crosslinking aid, in which the content of the crosslinking aid is equal to or more than 0.1 parts by mass and less than 2.0 parts by mass with respect to 100 parts by mass of the ethylene-based copolymer.

Methods of manufacturing electrochromic windows are described. Insulated glass units (IGU's) are protected, e.g. during handling and shipping, by a protective bumper. The bumper can be custom made using IGU dimension data received from the IGU fabrication tool. The bumper may be made of environmentally friendly materials. Laser isolation configurations and related methods of patterning and/or configuring an electrochromic device on a substrate are described. Edge deletion is used to ensure a good seal between spacer and glass in an IGU and thus better protection of an electrochromic device sealed in the IGU. Configurations for protecting the electrochromic device edge in the primary seal and maximizing viewable area in an electrochromic pane of an IGU are also described.

An electronic device module comprises: A. At least one electronic device, e.g., a solar cell, and B. A polymeric material in intimate contact with at least one surface of the electronic device, the polymeric material comprising an ethylene multi-block copolymer.

Typically, the polyolefin material is an ethylene multi-block copolymer with a density of less than about 0.90 grams per cubic centimeter (g/cc). The polymeric material can fully encapsulate the electronic device, or it can be laminated to one face surface of the device. Optionally, the polymeric material can further comprise a scorch inhibitor, and the copolymer can remain uncrosslinked or it can be crosslinked.

The invention relates to a polymer material comprising a mixture of: a base polylactic acid (PLA) polymer formed by between 60 wt.-% and 85 wt.-% L units and between 15 wt.-% and 40 wt.-% D units or between 60 wt.-% and 85 wt.-% D units and between 15 wt.-% and 40 wt.-% L units; and a plasticizer selected from the group containing citric acid esters, glycerin esters and derivatives, poly(alkylene ethers), oligomers of lactide or derivatives of lactic acid, fatty acid esters and epoxidized oils, representing between 10 wt.-% and 40 wt.-% in relation to the total weight of the polymer material.

Described herein are optically transparent and semipermeable windows composed of at least one layer of an amorphous crosslinked fluorinated copolymer. Also disclosed are a process and apparatus for three-dimensional continuous liquid interface production (CLIP) printing using the windows described herein. The amorphous crosslinked fluorinated copolymers have improved mechanical properties, thereby reducing the susceptibility of the window to brittle failures such as cracking and crack propagation. The gas permeable windows have superior durability and reliability compared with other available structures and compositions.
