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.

Wedge-shaped multi-layer interlayer with outer skin layers of varying thickness

An interlayer structure having a cellulose ester layer for use in bilayer laminates is described herein. The cellulose ester layer provides rigidity and support to multilayer interlayers comprising an array of different layers. Due to the diverse properties of the cellulose ester layers, the present interlayers can be useful in producing structural laminates having high stiffness and which possess good optical clarity for a variety of applications, including outdoor structural applications and HMI devices.

Laminated glass and interlayers comprising cellulose esters

A multilayer interlayer structure having a first and second polyvinyl acetal (poly(vinyl acetal)) layer and a cellulose ester layer having a thickness of at least 10 mils disposed between the first and second poly(vinyl acetal) layers. The cellulose ester layer can have a higher storage modulus and/or higher Tg than at least one of the poly(vinyl acetal) layers. The interlayer structure is useful to make glass panels having high stiffness and which possess good optical clarity for a variety of applications, including outdoor structural applications.

Resin compositions, layers, and interlayers comprising an acetoacetylized poly(vinyl acetal) resin are provided. Such compositions, layers, and interlayers can exhibit enhanced or optimized properties as compared to non-acetoacetylized poly(vinyl acetal) resins. The acetoacetylized poly(vinyl acetal) resins may be used in a layer or an interlayer for in an architectural application, or the acetoacetylized poly(vinyl acetal) resins may be used in a layer or interlayer, or combined with other layers, to provide an interlayer having good acoustic and other properties.

Esterified poly(vinyl acetal) resin compositions, layers, and interlayers having enhanced properties

An monolithic interlayer with high stiffness and when laminated into a glass panel, the glass panel exhibits good clarity, while maintaining the processability of a polyvinyl acetal, such as polyvinyl butyral resin used to make the monolithic interlayer. The monolithic interlayer comprising a polymer blend of:
