摘要:
A reactive hot melt adhesive has a glass transition temperature of from 45° C. to 100° C. The reactive hot melt adhesive includes the reaction product of: an isocyanate component and an isocyanate reactive component chosen from a polyester, a polyether, and combinations thereof. The isocyanate component and the isocyanate reactive component react in the presence of a styrene acrylic resin that is free of hydroxyl functionality and that is the reaction product of 60 to 80 wt % of one or more monomers chosen from C1 to C20 alkyl acrylates and methacrylates and 20 to 40 wt % of one or more monomers chosen from vinylaromatics having a vinyl moiety having 2 or 3 carbon atoms.
