<P>PROBLEM TO BE SOLVED: To provide a composition for reducing noise which can give excellent noise reduction performance, electromagnetic wave absorption performance and durability and if need, thermal conductivity and has small volatile component and has easily controllable surface tackiness and high productivity and to provide a noise reduction sheet obtained by curing the composition. <P>SOLUTION: The composition for a noise reduction sheet contains (A)-(C). (A) is a vinyl polymer having one or more groups on average expressed by general formula, -CO(O)C(R<SP>a</SP>)=CH<SB>2</SB>---(1) (in the formula, R<SP>a</SP>expresses a hydrogen atom or a 1-20C organic group) per one molecule and 0.8 or more groups expressed by general formula (1) at the molecule end, (B) is an initiator and (C) is soft magnetic filler. <P>COPYRIGHT: (C)2009,JPO&INPIT |
