POLYVINYL ACETAL AND CELLULOSE ESTER MULTILAYER INTERLAYERS |
| 摘要 |
A multilayer interlayer structure having a first and second polyvinyl acetal (poly(vinyl acetal)) layer and a cellulose ester layer having a thickness of at least 10 mils disposed between the first and second poly(vinyl acetal) layers. The cellulose ester layer can have a higher storage modulus and/or higher Tg than at least one of the poly(vinyl acetal) layers. The interlayer structure is useful to make glass panels having high stiffness and which possess good optical clarity for a variety of applications, including outdoor structural applications. |

1. A multilayer interlayer comprising:
(A) a first polyvinyl acetal (“poly(vinyl acetal)”) layer comprising poly(vinyl acetal) resin; and (B) one or more cellulose ester (“CE”) layers comprising cellulose esters; and (C) a second poly(vinyl acetal) layer comprising poly(vinyl acetal) resin; wherein at least one CE layer is disposed between the first and second poly(vinyl acetal) layers. |
