Abstract:
A polymer interlayer comprising a layer comprising a poly(vinyl acetal) resin having a residual hydroxyl content and a residual acetate content, and a plasticizer, wherein the residual hydroxyl content, the residual acetate content and the plasticizer are selected such that the polymer interlayer has at least one glass transition temperature less than about 20° C. and a peak tan delta of greater than 1.29, and a glass panel having a configuration of 2.3-mm glass//interlayer//2.3-mm glass and at 20° C. has a transmission loss, TL w , of greater than 41 decibels as measured by weighted average sound transmission loss at 2000 to 8000 Hz, and a transmission loss, TL c , of greater than 38 decibels at the coincident frequency is disclosed.

Claim (Index 13):
A polymer interlayer comprising:\n a first layer comprising a first poly(vinyl acetal) resin having a first residual hydroxyl content and a first residual acetate content, and a first plasticizer; and a second layer comprising a second poly(vinyl acetal) resin having a second residual hydroxyl content and a second residual acetate content, and a second plasticizer; a third layer comprising a third poly(vinyl acetal) resin having a third residual hydroxyl content and a third residual acetate content, and a third plasticizer; wherein the residual hydroxyl contents, the residual acetate contents and the plasticizers are selected such that the polymer interlayer has at least one glass transition temperature less than about 20\u00b0 C. and a peak tan delta of greater than 1.29; and wherein at least one of the difference between the first residual hydroxyl content and the second residual hydroxyl content, the third residual hydroxyl content and the second residual hydroxyl content, the first residual acetate content and the second residual acetate content and the third residual acetate content and the second residual acetate content is at least 2.0 weight percent, and a glass panel having a configuration of 2.3-mm glass//interlayer//2.3-mm glass and at 20\u00b0 C. has a transmission loss, TLw, of greater than 42 decibels as measured by weighted average sound transmission loss at 2000 to 8000 Hz, and a transmission loss, TLc, of greater than 41 decibels at the coincident frequency.
