POLY(VINYL ACETAL) RESIN COMPOSITIONS, LAYERS, AND INTERLAYERS HAVING ENHANCED OPTICAL PROPERTIES

摘要

Resin compositions, layers, and interlayers comprising two or more thermoplastic polymers and at least one RI 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.
