Abstract

아세탈기의 탄소수가 4~6이고, 그리고 아세틸기가 결합하고 있는 에틸렌기의 평균치의 주쇄의 전 에틸렌기에 대한 몰분율이 8~30몰%인 폴리비닐아세탈수지(A)와 가소재로 이루어지는 적어도 하나의 층(A)과, 아세탈기의 탄산소수가 3~4이고, 그리고 아세틸기가 결합하고 있는 에틸렌기의 평균치의 주쇄의 전 에텔렌기에 대한 몰분율이 4몰%이하인 폴리비닐아세탈수지(B)와 가소제로 이루어지는 적어도 하나의 층(B)이 적층되어 있는 접합유리용 중간막이다.
음에너지가 효과적으로 열에너지로 변환흡수되고, 특히 2000㎐부근의 중고음역에 있어서 코인시덴스 효과에 의한 차음성능의 저하가 효과적으로 방지된다.
