Abstract
Official abstract text for this publication.
An acrylic composition, which has excellent flexibility at low temperature and can form a formed body whose adhesion at room temperature is suppressed, the formed body of the acrylic composition, a key sheet of a mobile telephone, and a light guide obtained from the formed body are provided. The acrylic composition contains specific long chain di(meth)acrylate (A) and mono(meth)acrylate (B), and the glass-transformation temperature (TgDMS) of the polymer of the acrylic composition is 40° C. or less. The formed body is obtained by polymerization of the acrylic composition, and the key sheet of the mobile telephone and the light guide are obtained from the formed body.
First claim
Opening claim text (preview).
The invention claimed is: 1. An acrylic composition, comprising: a long-chain di(meth)acrylate (A) represented by Formula (1): CH 2 ═CR 1 —COO—(X)—OCO—CR 1 ═CH 2 (1); and a mono(meth)acrylate (B) comprising at least one selected from the group consisting of methyl (meth)acrylate, n-butyl (meth)acrylate, tridecyl (meth)acrylate and tetradecyl (meth)acrylate, wherein, in the Formula (1), (X) is a bivalent group having a number average molecular weight (Mn) of 500 or more…
