摘要： 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.

摘要： 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° 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.

摘要： Resin compositions, layers, and interlayers comprising two or more thermoplastic polymers and at least one Rl balancing agent for adjusting the refractive index of at least one of the resins or layers is provided. Such compositions, layers, and interlayers exhibit enhanced optical properties while retaining other properties, such as impact resistance and acoustic performance.
