A method for recycling of glass laminates (10) is disclosed. The glass laminates (10) comprise at least one glass layer (30, 40) and at least one polymer layer (20). The method comprises mechanical removal of at least part of the glass (30, 40), placing residual waste (350) with glass particles in a vat (360) comprising a separation fluid (375) to produce a mixture of glass particles and polymer pieces from the residual waste, from which the polymer pieces can be screened off, washed and dried for reuse. The separation fluid (375) comprises water and at least one alcohol.

Multiple layer interlayers having enhanced optical and acoustic properties are provided, along with methods of making and using the same. Interlayers as described herein may include at least two outer skin layers and an inner core layer, with one of the outer skin layers having a different thickness than the other at one or more locations along the interlayer. The multi-layer interlayer may also exhibit acoustic properties and, in some cases, may have an overall wedged thickness profile. Additionally, in some aspects, interlayers and laminates formed therefrom may also provide reduced infrared energy transmission, without sacrificing acoustic and/or optical performance.

A multi-layer polymer film comprising at least one middle layer A, the polymeric constituents of which are soluble in aqueous solution, and at least one substantially water-impermeable covering layer B or C arranged above and/or below the at least one middle layer A, wherein the layers A, B and C independently of each other in each case comprise at least one thermoplastic polymer and at least one of the covering layers B and C comprises at least one polyhydroxyalkanoate. Processes for the production of the multi-layer polymer film according to the invention and its use for the production of molded parts, films or bags are furthermore presented and described.

A dry prepreg of fibrous textile/thermoplastic with handling characteristics highly compatible with robotic handling and a method for making at least one dry prepreg and forming the at least one dry prepreg over a mold form. The method also includes using the at least one molded dry prepreg as at least one sub-laminate in a thermoforming process. The methods include CMC preforming processes which can be automated though the use of robotic handling devices.

Presently described are methods of making an article comprising providing a structured film (1100) comprising a thermoformable planar base (212) layer and a structured surface (116, 216) layer disposed on a major surface (1200) of the planar base (212) layer wherein the structured surface (116, 216) layer comprises a different organic polymeric material than the thermoformable planar base (212) layer, and thermoforming the structured film (1100) into a thermoformed article (1000). Also described are thermoformed and thermoformable articles.

Processes are disclosed for separating a first layer from a remainder of a tapered multilayer interlayer sheet, in which the tapered multilayer interlayer sheet is heated, and thereafter the first layer is separated from the remainder of the tapered multilayer interlayer sheet by pulling the first layer and the remainder of the tapered multilayer interlayer sheet in different directions, in a defined orientation, without the tapered multilayer interlayer sheet wrinkling or tearing.

An interlayer film for laminated glass, comprising two or more resin layers, wherein at least one of the resin layers has a glass transition temperature different from that of the other resin layer or layers, and wherein the two or more resin layers include a low-Tg resin layer having the lowest glass transition temperature among the two or more resin layers, the interlayer film for laminated glass has a thickness ratio of the low-Tg resin layer to the entire interlayer film, R(x), wherein x [mm] represents a coordinate on a straight line from one end of the interlayer film to the other end, and the difference between the maximum and minimum values of the thickness ratio R(x) is 8% or less.
