Embodiment

[0085] Prepared by mixing and melt extruding 100 parts of poly(vinyl butyral) resin and various levels of plasticizer, and other common additives (as described above) as shown in Table 1 Exemplary core layers of the present disclosure are shown (referred to as "disclosed layers" and shown below as DL 1-8 Table 1 middle) and control or contrast core layers (referred to as "contrast layers" and shown below as CL 1-2 Table 1 middle). then use Table 1 The core layer shown in to construct as Table 2 and table 3 Various multilayered interlayers are shown in and described more fully below.

[0086] By comparing a multilayer (three-layer) interlayer having a blend of two resins with different residual hydroxyl content and at least one plasticizer in the core layer (referred to as the "disclosed interlayer") to a multilayer (three-layer) interlayer having only a single Multilayer interlayers (referred to as "comparative interlayers") of a core layer formed of a resin (fixed resi...

Abstract

A multilayered intermediate layer comprising a hard skin layer and a soft core layer is disclosed. The multilayered intermediate layer includes: a first polymer layer (skin layer) comprising plasticized poly(vinyl butyral) resin; a second polymer layer (core layer) comprising two or more a blend of plasticized poly(vinyl butyral) resins having different residual hydroxyl content, wherein the plasticizer is a high refractive index plasticizer having a refractive index of at least about 1.460; and optionally, a third A polymer layer (skin layer) comprising a plasticized poly(vinyl butyral) resin.

Description

technical field [0001] The present disclosure relates to the field of polymer interlayers for multilayer glass panes and multilayer glass panes having at least one polymer interlayer sheet. In particular, the present disclosure relates to the field of polymeric interlayers comprising a plurality of optical defect-resistant forming thermoplastic layers. Background technique [0002] A multilayer board generally refers to two substrates (such as, but not limited to, glass, polyester, polyacrylate, or polycarbonate) and one or more polymer interlayers sandwiched between them. Laminated multilayer glass panels are commonly used in architectural window applications, in windows for motor vehicles and aircraft, and in photovoltaic solar panels. The first two uses are often referred to as laminated safety glass. The main function of the interlayer in laminated safety glass is to absorb the energy generated by an impact or force applied to the glass so that the glass layers remain ...
