Hot melt adhesives for electrical devices

Abstract

The present invention provides a hot-melt adhesive having excellent solvent resistance and excellent adhesion to an adherend (in particular, a polyimide film) containing a battery electrolyte solution therein, and which can Contributes to the improvement of the performance of the electric device; the present invention also provides an electric device prepared by using the hot-melt adhesive. The hot-melt adhesive for electrical devices comprises an olefin-based modified polymer (A), wherein the olefin-based modified polymer (A) is a modified polymer with a silicon-containing functional group; The hot melt adhesive of the device has excellent resistance to the electrolyte of the battery (i.e., electrolyte or solvent resistance), and also has improved hot melt adhesive resistance to the battery containing the electrolyte therein. Adhesion of stickies (plastic films such as polyimide films).
