ABSTRACT:
Methods, apparatuses, and systems for manufacturing a hot melt adhesive containing an adhesion promoter in a continuous mode include supplying a melted, hot melt adhesive to a mixing device at a first predetermined rate while simultaneously supplying an adhesion promoter to the same mixing device at a second predetermined rate to form a homogeneous admixture containing the hot melt adhesive and adhesion promoter. The hot melt adhesive/adhesion promoter mixture is subsequently reacted in at least one tubular reactor at a predetermined temperature for a predetermined residence time to allow the adhesion promoter to chemically bond with the hot melt adhesive and form an adhesive-promoter-treated hot melt adhesive. The adhesion-promoter-treated hot melt adhesive is collected in a product receiver and may be further processed.
