BASE POLYMER FOR HOT-MELT ADHESIVE AGENT, AND HOT-MELT ADHESIVE AGENT

摘要

Provided is a hot-melt adhesive agent which satisfies both a solidification rate and an adhesion property. A base polymer for a hot-melt adhesive agent, which satisfies the following requirements (1) and (2): (1) the tensile elastic modulus is 400 MPa or less at 23˚C; and (2) the crystallization half time is 20 minutes or shorter at 23˚C.
