Multilayer interlayers having high Tg and high modulus

A multilayer interlayer structure having a low Mw/high Tg layer and a high Mw layer, the interlayer having a high E′ modulus and a higher Tg. The high Tg layer has a Tg of at least 50° C. and a weight average molecular weight of not more than 160,000. The high Mw layer has a molecular weight greater...

More Information
Summary:A multilayer interlayer structure having a low Mw/high Tg layer and a high Mw layer, the interlayer having a high E′ modulus and a higher Tg. The high Tg layer has a Tg of at least 50° C. and a weight average molecular weight of not more than 160,000. The high Mw layer 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.
