Polymeric interlayers for use in making multiple layer panels having a unique balance of properties are provided. Single and multiple layer interlayers according to various embodiments of the present invention can be used to form multiple layer panels that exhibit both enhanced rigidity and improved impact resistance, while still retaining desirable optical performance. Interlayers and multiple layer panels of the present invention may be particularly suitable for use in a wide range of applications, including, for example, in many indoor and outdoor architectural and structural applications.

Polymeric interlayers and multiple layer panels made therefrom exhibiting enhanced properties and performance

A polyvinyl acetal poly(vinyl acetal), such as polyvinyl butyral, resin formulation, a method of extruding poly(vinyl acetal) resins, and related materials and products that provide for monolithic poly(vinyl acetal) sheets and glass panes having high Tg of at least 50&#xb0; C. and high modulus at acceptable rates as indicated by their high melt flow index. This is made possible by a reduction in the amount of plasticizer while using a low molecular weight resin not to exceed 160,000 to obtain a thermoplastic resin having a high melt flow index and high Tg. The articles made with these monolithic interlayer sheets can be used in applications that require good modulus at outdoor temperatures.

High Tg monolithic poly(vinyl acetal) sheet

A multilayer interlayer structure having a low M/high Tg layer and a high Mlayer, the interlayer having a high E' modulus and a higher Tg. The high Tg layer has a Tg of at least 50&#xb0; C. and a weight average molecular weight of not more than 160,000. The high Mlayer has a molecular weight greater than 160,000. The interlayer structure has increased stiffness without having to increase its thickness, and has an increased Tg to enable the structure to be used in applications that require good modulus at outdoor temperatures.
