The reactive hot melt composition, the reactive hot melt composition composition for preparing a film-shaped hot melt adhesive

摘要

A composition for preparing a reactive hot melt composition comprises (a) a thermoplastic polymer which comprises a polyolefin having an epoxy group, and (b) a radiation polymerizable component containing (b-1) an aliphatic alkyl (meth)acrylate and (b-2) an acrylic compound having a functional group reactive with an epoxy group. A reactive hot melt composition is obtained by polymerizing this composition so as to polymerize the radiation polymerizable component. The reactive hot melt composition which can be easily hot melt coated, cross-linked quickly in the absence of radiation or moisture after bonding adherends, does not form moisture during cross-linking, and has high flowability during hot melting.
